Recently, my server has been running real slow and I don't know why... I've not noticed any increase in traffic (In fact it goes slow with no traffic on it...), what are some things I can look at to try and diagnose the problem? I know next to nothing about *nix so please speak in great detail.
Anytime I restart Apache, it loads quick for a few seconds then gets slow again...
Here are the top few processes listed on the process manager: .....
I have a website on a linux-server working fine with PHP/Apache. The page loads a lot of css/js/image-stuff (total 84 requests, 220k), it takes about 4 secs to load via internet.
Now I'm testing the same page locally on a Win7-64-system (Apache 2.2, PHP 5.4). The system is not very slow (8 GB RAM, SSD, i7-CPU), but loading the same page as above takes about 50 secs.
The Q is: What might be the problem?
- I turned off firewall and anti-virus.
- I used mod_status: 150 threads, max. 11 seems to be used during the loading of the page.
- I tried php5apache2_2.dll with TS-PHP 5.4 and mod_fcgid.so with NTS-PHP 5.4, but the loading-time kept almost the same.
Looking at the "network-tab" in FF or Chrome, I found that a lot of subqueries get a timing like this:
Blocking: 11.96 s Sending: 0 Waiting: 1 ms Receiving: 6ms
So the loss of time seem to be in the "blocking"-section. I first thought of something like "limited number of TCP-Connections", but as said above, on the same system the page is remotly loaded fast enough almost without these "blocking"-parts.
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
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?
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 have a few different types of servers, all of which came with their own KVMoIP setup, aka DRAC and iLO which have worked only so so since their deployment. The HP iLO has performed absolutely flawlessly but the DRAC on the other hand has been nothing less than a complete nightmare.
I'm looking for a KVM over IP system that we can connect to multiple servers, mainly Dell, that is 100% reliable and completely stable. Not something that will be giving Java errors randomly when you actually need it to work.
So far I've came across the Raritan Dominion KX II which looks pretty promising. Is there any other KVM over IP systems or manufactures that I should look into? Has anyone used this and can you comment about its reliability?
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). # Performing check of passwd files... # Checking entries from /etc/passwd. --WARN-- [pass014w] Login (firebird) is disabled, but has a valid shell. --WARN-- [pass016w] User oident has / as home directory --WARN-- [pass015w] Login ID sshd does not have a valid shell (/usr/sbin/nologin). --WARN-- [pass015w] Login ID sync does not have a valid shell (/bin/sync). # Performing check of PATH components... --WARN-- [path009w] /etc/csh.login does not setenv an initial setting for PATH. # Only checking user 'root'
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).
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 have got a dedicated server running Fedora Core 7.
My problem is that I am trying to run yum updates using the default repos and it failes to respond and check any mirrors?
I have tried to disable ipv6 and changed some tcp timeout settings along with the resolver.conf name servers and has appeared to fix the wget timeouts but yum is still slow.
I have a VPS acct with Plesk, am peaking out my system ram at 128mb. Host said to allocate ,ore = purchase more. What I would like to do is hunt down where I am using the most of it. I have 8 sites (non that are too big). Most of them are wordpress sites.
Would caching help? Not sure where to look to find this out.
well i purchased a new dedicated server it has 4gb ddr2 ram and quad core Q6600 cpu. and on 100mb shared. i havent even yet added any web site to it. but sometimes i get timeout when using whm. its hella slow :/ thats very strange and rare on new server.
frends now iam haveing dedicated server with pentium-4 and RAM is 2GB,my site online members is more than 100 members,now i feel slow in server,what i have add extra RAM or any chage in server
the FTP was goosed on a personal server before and I was on my way out with the bitch, so I decided to get PSM to sort it out for me.
Came back about 5 - 6 hours later and it hadnt been fixed. No problem though as I would just do it myself. Anyway just as I logged into SSH to get it done, they did it, cheers.
I wanted something enabling on the FTP at the request of a friend but wanted to watch some TV and as I can't seem to use the laptop and watch TV at the same time nowadays, decided to get PSM to do it (its only to enable resume on the FTP, so its a simple request).
Anyway to cut the story short, the ticket was submitted 6 hours 33 minutes ago and still no response. I wont do it myself now as I want to see how long it takes them to respond, it will be interesting as they have already failed to meet their 6 hour response guarantee.
Other then tonight I can't fault PSM, whenever I use them (which to be honest is maybe once every 5 months or so) they are great and usually very speedy, but tonight its just sooooo slow, its really unusual. Anyone else noticedc this slowness tonight?
For those of you that complain about the slow loading speed of your sites due to being on over-loaded servers or over-sold bandwidth, why do you think that the discounted rate is worth the loss of customers that you might earn if your site loaded faster.
Have you ever given your sites a try on a quality host where your site loaded faster? You might be surprised at how much more effective your marketing was when surfers stay around long enough to see your site load.
Some times in the effort to secure such a great deal and save a penny, you wind up loosing a dollar, it might not make a difference to all of you but some will be surprised at the ROI for a bit better hosting!
Ive been getting the following System Warning every hour since I set the server up 5 days ago and Google hasn't been a lot of help in tracking down what it means and if I should be concerned. Im hoping someone here can point me in the right direction. Im running Windows 2003 Web Edition.
