Site Slow

It was able to handle over 5000 connection without problem.
When checked the log, can not find anything suspicous.

my site is terribly slow, especially if there are several users accessing it at once.
Is there a way to to find out what exactly is slow, so I know what to tackle?
Since there is no caching at the moment, I think that is a good point to start.
The reason that there is no caching, is because Internet Explorer kept showing stale content, whatever I tried. How do you make sure that IE doesn't cache the dynamic pages?
This also means that images are not cached and pages with several images, seem to load a lot slower, sometimes not even showing all images the first time the page is loaded.
Does anybody know what I can do to improve on this?

I had an VPS in SLHost and experiencing fall downs and slow server... now I moved and I check that the VPS is fast and great, but my sites are loading too slow...
I mean the connect time is too long; the time between connect and sending first byte goes from 5 to 12 seconds! My provider can't find what's wrong and I'm a little lost in this

I have a website www.officegofor.ca. The site takes a very long time to load. I don't think it's because of the server's connection speed. What would be the best way to diagnose the problem? What could the problem be? I noticed that it get's slower and slower with time and when I restart apache it's faster (but still not fast enough).

I rented a server from VD a month ago and hosted some of my websites. But I'm constantly noticing that my websites are loading very slow. How can I check if other users are experiencing the same problem, or if the problem lies with my Internet connection?

our VPS hosting company did an upgrade the other day and now something is wrong with our home page, it takes about 30sec to load. They keep saying its a php problem, but the scripting is fine, the engine is fine and the only thing that changed is that they did an upgrade.
They don't seem to be able to grasp the problem, and it is making my boss go nuts. A web guy a know said it definately had to be something at their end, and everyone else is at a loss.

My machine is pretty good. Here are the specs:
Intel Xeon-Woodcrest 5148-DualCore
3 gigs of ram
250GB Western Digital WD Cavia
I run a forum with a modest amount of traffic along with a content management system handling the other sections of the website. I'm pretty sure the forum isn't the problem though.
The server load for this machine is almost never above a 1. Right now as I type this the load is at 0.17, but it's unbearably slow! Taking up to 16 seconds to load a single page.
What could be causing this? I'm a server n00b. Is there a setting I should be doing to one of my servers configuration files to make it run faster?
My website gets 30-40,000 visitors a day and these problems always occur during peak hours. It would be easier to deal with this though if not for the fact that the server load is always so low. How is it possible for the site to get so slow while the server load is always so low?

I wanna know if upload media to server for streaming will slow your site down?
Reason is that I have a few audio books on my server for my members to listen to, and I have a feeling that my site is using more and more resources and its getting slower and slower each day.

I moved from shared host to VPS a few days back. Since the move, the site becomes slow during particular time of the day. It appeared to be an issue of cron run by their another client and after promising that they would move that client to another node (I have spent more than 25 days to follow up on this till now) they backed off from their words but informed me about an alternative. Now, they say that the cron of that client was executing many scripts and they have spaced those scripts.
I am looking for a long-term host and was wondering:
1. VPS provides a minimum guaranteed stuff so what is the use of that guarantee if one client can make the server crawl (imagine 5 minutes or more to open a site).
2. Can a host be trusted who does not honour words.

I have built a database driven site with PHP & MySQL. Pages download quicker on some connections than other (obviously), however this is not due to connection speed. The web host server seems to respond very slowly to my boss's network (which is on a proxy server). Could it be that this problem is related to the web host? i.e. could it be that the web host is unequipped to deal quickly with this type of network?
On my home connection (2Mbps), pages often download instantly, however occaisionally I have to wait 10-20 seconds to receive the page from the host.
Finally, could you recommend an excellent web host to use with our site? My boss wants to offer a professional service where server response is quick. We are based in the UK.

I've got 25 domains on a Virtuozzo/Plesk8.6/CentOS5 VPS. Each domain has one up-to-date install of WordPress, most have very little traffic (average 200mb per month), maybe 2 domains get 5-7gb traffic per month.
I monitor port 80 connections and rarely see more than 10 at a time.
That should in my opinion be no problem at all for a VPS with 768mb guaranteed ram and 2.4ghz cpu. I've got 30gb hard drive spare too.
But.... about 8 or 10 times a day it grinds to a complete halt: server load at 500-1000%, sites timing out, plesk takes 3mins to load, often I can't even connect with SSH, and the plesk web server, apache
INSERT INTO module_watchdog_sys_stat (time, type, value, service_id) VALUES(FROM_UNIXTIME(1226404705), 'MAINMEM_USAGE', 17472, 11);
80 seconds sounds like a huge amount of time for a MySQL insert to me! Does anyone know if this is likely to be the cause of my trouble? Some problem with Plesk and the database? Or could it be something else?

Attached is a (badly) drawn diagram of two sites, connected by a vpn.
The site to the left, is network 10.0.0.0/24 which runs a linux server as the router for the network.
The site to the right, is network 10.1.0.0/24 which runs a windows 2003 server as the router for the network.
Now, my problem is, the clients behind the windows 2003 server can ping any machine on the first network because i setup a static route to route all traffic to 10.0.0.0/24 over the vpn interface.
now, my problem is, only the linux server can ping any machine on the windows 2003 network, any client behind the linux server cant seem to route over the interface.
I have the following route on the linux server: .....

Starting point: a working site using a shared IPv4, dedicated IPv6, and SSL. HTTP and HTTPS work, the latter only using SNI of course.
The good news: If I simply allocate an IP resource of 1 to a subscription it is pulled from the pool, assigned to the service node, assigned to the web site, DNS is updated, and the site is automatically changed to using a Dedicated IPv4 and Dedicated IPv6.
The bad news: visitors land on the default web site of the service node, with the default SSL certificate.
Other info: I can't ping the new IP, even though it shows in "ip a l" and /etc/sysconfig/network-scripts/ifcfg-eth0:0. [edited]
After the IP assignment, it is still installed, and /etc/httpd/conf/plesk.conf.d/ip_default/domainname.conf shows the new certificate is being used.
However, a second set of VirtualHost entries is created in server.conf for this IP for ports 80 and 443, with NameVirtualHost enabled on the new IP. The port 443 entry uses the default certificate. Apache's setup this default VirtualHost entry will override the web site configuration because Apache is listening on port 443 with the wrong cert.
If I go to "Change webspace settings" and toggle to Shared IPv4, Dedicated IPv6 the site works again via HTTPS, and Dedicated IPv4 and Dedicated IPv6 breaks it again. Setting the SSL cert to None and back again does not work.
Setting the SSL cert to None, changing to a dedicated IP, and enabling SSL results in the server being inexplicably inaccessible...browsers no longer connect to either the default site or the correct site, and I don't see any entries in the vhosts's logs.

In these conditions how much difference can lighttpd can do as compared to apache for keeping my 600 MB Ram VPS host constant.

I'm on a short assignment to inventory and manage the fixed assets of a small company, and we've just bought a web-based database for this purpose. While I'm pretty good at administering/running local databases, the web part has me stymied. Our company is between IT people, and there's no one on site with any more idea than I have about what's going on!!
Here's what I have so far:
--The company has a website which I'll call "ourwebsite.org" -- which I think, from searching the IP address the website points to, is hosted by HostMySite.com.
--There's also a record in DNS Management with the same name (ourwebsite.org), but pointing to our little server's local IP address.
--I need to find a way to get my database -- which I can access on the network at (server's IP address)/database (ie 0.0.00.0/database) -- online. I tried creating records in DNS Management (for ex., assets.ourwebsite.org) that point to our server's IP (the one that, if I type it in on the network, I can get to the site I'm looking for), but get generic "can't find the page" or "can't connect to the server" errors, even after 72 hours, when trying to access it from off the network.
--If I browse to assets.ourwebsite.org/database on the server itself, I get to the website! But if I go to that page from any other computer, on or off the network, it doesn't work.
--The Server is running Windows Server 2003
So, what are my options? Do I have to talk to the HostMySite.com people to add this page? Shouldn't I just be able to use my server's name (ourcompanyadc.ourcompany.org) and have that route to the server? What's going on here! Is there a simple way to get a tiny local-server-hosted website online outside of the network?

I just transferred a domain from one cpanel box to another.
Now, that site is showing someone else's page. I've seen this happen before, but I cannot remember the fix.
the virtual host in httpd.conf is fine, shows proper IP, username, docroot, etc
Dns zone is fine as well.
The domain is using the server's main IP, so that's not the cause.
Centos 5 / cpanel 11 / apache 1.3 / php 4x

At 15.00 PM (+1 hours here) my isp rebooted the hardware node. After the reboot there were some issues, they think it is possibly a DDoS Attack. They said the load on the host node was in the hunderds and my VPS was stopped because of the reboot and when I started it, HyperVM first told me it was not possible and after a few tries it started finally.
But the load was very high, and it still is. How can I check what the problem is that creates the high load?

I did nothing but my whole server got slower.
Especially the sshd and mc.
I solve the sshd problem cos I edited the conf file with UseDNS no so it faster right now but I couldnt do anything with mc.
I have to wait about 15 seconds to load it.
Any suggestion?
or any ideal why my server become slower?
System: Debian 4.0
kernel: grsec 2.6.19-1
Till today morning its okey.
Oh, yes, I run tiger and got the following message in log:
09:50> Beginning security report for atdn.us (GNU/Linux Linux 2.6.19.1-grsec).

I modificated this to the correct one (I mean I try to solve this warnings) but when I noticed that my machine becmome slower, I recover everything.

I have an ASP.Net + SQL Server 2008 Express website I was hosting with DiscountASP.net. Their service seems pretty solid, and I didn't have any issues hosting with them. Customer support was quick and knowledgeable.
However, I had noticed for quite some time that the website seemed pretty slow. Please note that the website isn't live yet, so it was only me and a colleague who were accessing it. I was accessing the website from Dubai, UAE and he from Doha, Qatar. Therefore traffic/load definitely wasn't the problem.
We tried an instance of the website on a VPS (the DB was still running on DASP), and it was blazing fast! The difference in speed was quite significant and sustained. What could the reason for this be? Is it because we can't expect good speeds from shared hosting? Or should I report this issue to DASP?
I would be paying around 5x of what I'm paying right now ($100 instead of $20) if I switched to a VPS, but if there are definite advantages, I would be willing to do so. I don't expect large volumes of traffic on the website for quite a while.

I have a problem with my company's web hosting solution: occasionally we go through periods where we cannot seem to access our webpages very quickly. In different browsers (IE, Firefox) it takes literally minutes to load a single page. Most of the time the pages load very quickly from inside our office or outside.
Our self-hosting configuration is:
Windows XP Pro. w/ SP3
Apache 2.2.11 with PHP5.2.9-2
Norton Internet Security
Our internet connection is 10Mbps down / 900 kbps up cable behind a DLink router with port 80 forwarded over to the web server. Each page of our site is relatively small in size.
The same computer server as a mail server for about 10 email addresses.
When we encounter this problem, restarting the Apache service never seems to help, but restarting the computer does seem to help. XP was put on the computer with the latest updates about 3 weeks ago, so I am not concerned about spyware, particularly since this computer is only used as a server.
Does anyone have any troubleshooting steps to determine what the problem is? We don't have hundreds of visitors at a time in traffic as far as I am aware.

I own the website [url]and it's hosted at Host Excellence. Recently there have been some downtime periods, and most importantly, I have noticed that downloads are very slow. For instance, when I download a file such as [url]I get an approximative transfer rate of 100-150 KB/sec (whereas most other sites download at 500 KB/sec or more). First of all I'd like to know if you guys get similar results, and what do you recommend? I have contacted my host about it, they seem to deny the problem. Should I switch? What to? I need something reliable and fast.

After my bad experiences with the other provider, I decided to go with GeekStorage.com for my hosting needs. I found plenty of positive reviews for them but so far, it doesn't look good :-/
The support was fast enough, but not really helpfull.
My basic problems, so far, are:
1. The VPS is _really_ slow. Simple operations like listing (ls) the contents of directories with 4-5 files takes around 1~1.5seconds. Editing /etc/vim/vimrc with vim takes around 3 seconds (to open, I mean).
2. While trying to install phpmyadmin from the default ubuntu repository took me almost 10 minutes, from downloading to installing the packages. Something my old Dual P3 (yes, pentium 3) did in less than 2 minutes. Accessing the phpmyadmin page (with a web browser) took around 3 seconds, and no, I don't mean loading the database scheme and stuff, just the login screen. It just stood there for 3 seconds, then instant load. No, it wasn't a DNS problem. My browser was just hanging at "Waiting..."
3. Bandwidth is _really_ low. Tried downloading different files located all around the world and I never seen more than 300k/s, max. Sometimes it drops to a painfull 150k/s and just stays there.
4. Timeouts. First night they got my VPS up I had small downtime periods. I was trying to edit the DNS files and I had like 20 disconnects in 1 hour. The connection was working for 2 minutes, then *poof* dropped for another 2 minutes.
5. The virtualization. I can't install simple software as pureftpd. All I get is "Jan 4 20:38:21 vps pure-ftpd: (?@?) [ERROR] Unable to switch capabilities : Operation not permitted". Tried different workarounds (trying to avoid recompilation with --without-capabilities) but nothing worked.
As answers, all I got so far is:
- for the connection problem:
"Could you please provide the results of a traceroute when this problem is occurring? We will forward it to the DC and see if they can determine any network issues. Thank you, and apologies for the trouble."
Got the answer 1 hour after I asked them if there's something wrong, but it was too late... the problems were gone, for the moment.
- the slow response from the vps:
"2-3 seconds is understandable during peak hours, however we have not seen this issue come up on node3 since the server was rebooted recently. If the issues arise again
please let us know, we will check on the cause."
I *almost* understand about the peak hours, but it's not normal. I remember this was an issue with *shared* hosting. This was one of the reasons I got a VPS in the first place.
Basically they're telling me that during peak hours my customers will have to wait 3 seconds for my websites to load. You know what the average user does after waiting that many seconds for a page to load? Closes the browser or types another address.
I have the VPS512 plan (the $55 one + $3 safetyweb protection) + extra 50% bandwidth and disk space. My VPS is located on NODE3.
Anyone else experiencing the same issues (maybe on another node?) I'm still hoping for this issues to go away, maybe it's something temporary, but if this happens for the whole week, I'll definatelly ask for money back (they have a 60day return policy).

Anytime I restart Apache, it loads quick for a few seconds then gets slow again...

I had configured webserver on one of my CentOS server. It worked fine for few months but after sometimes it started giving problem. I was not able to browse website. The I found that it was timing out so I increased timeout period from php and the website started working.
But still the website is taking 30-35 seconds to load. I checked the server but I couldn't find any solution. Please guide me to get this resolved.

I noticed today that SSH is taking longer to log into, I have tried by password and key but they just as slow as each other.
Once I am logged in, it is fine.
I have tried restarted SSHD via WHM but it makes no difference. Trace route looks ok and all other services seem fine as well.
Server load is around 0.00 and around 500mb ram spare.
