I have a website that I recently moved to a dedicated server. Before hand I had the website hosted with 2 other hosting companies (not dedicated).
I decided to go to a dedicated server because the website ran extremely slow or even went down due to traffic.
With the dedicated server I am having the same problem with the same amount of visitors online. This usually occurs with aprox 250 members online.
I know nothing about servers and have no idea how to cure this problem or if possibly it could be a setting in the server. However this is killing my website because new people are unable to register because of site coming down from traffic.
Today, without any change on the server side my single running website on my server started running low. After checking the running processes I realised I have these 8 processes running with high cpu load something that didn't had before.

apache error log doesn't show any warnings, errors.
But in the /var/log/httpd/error_log it is showing a long list of same error i.e" an unknown filter was not added :PHp".in this way my server is responding very slow for ftp and while accesssing through http.will u pls help me to solve this problem.
I am migrating my sites from a Xen based Centos 5.3 + cPanel/WHM instante to another Xen based cPanel/WHM solution with Centos 5.3 64-bit. I am having issues with easyApache now after it was successfully ran for the first time.
It does not time out however even the profile selection screen takes well over 10 minutes to get to once easyApache is initiated. Once the profile selection is made it is still slow moving to the customization screen.
The server is neither overloaded, nor out of memory. I have actually executed /scripts/checkperlscripts in hopes that it would identify something. I am planning to remove /home/cpeasyapache folder however I am not confident whether this is the right approach or not.
My sites have been receiving a little more traffic these days (but not too much) and it seems my vps is slowing and at times vbulletin/wordpress page doesn't loads or loads a bit sluggishly (refreshing the page gets rids of not loading issue but not sluggishness).
So I logged into Virtozzo and saw the following QOS alerts:

My Cpanel VPS has around 384MB of dedicated ram and around 896Mb of burst Ram. At any given time, there is at least 150Mb of free dedicated RAM. So based on this, are these values correct or they need to be changed or do I need to look for something else which might be causing this problem?
If you check out [url], you can see that its not running super fast. The load is nothing, iostat, vmstat, etc don't show anything out of the ordinary. Is there anything else I can do to see what might be causing it? Am I just in need of some good mysql optimization?
I have a client who has 3 to 4 websites. His websites are database driven mysql. When we transfered to a new server everything works. Then he requested a iconv and GD installations. Then it was installed. Now all of his sites is impossibly to view but its up. The rest of the clients are doing just fine. What do you think is the problem? we recompiled php several times already same thing.
For about the last two weeks I've had issues connecting with the website that I help run www.learnoutloud.com from my home connection which is Time Warner Cable Internet connection in Los Angeles. I'm on a Dell laptop Inspiron 6000 running Windows XP. I'm always able to connect to the site but what's happening is the page will get hung up on loading a single image usually and then it will take about a minute just to load that last image. And sometimes the page won't load at all, but all it takes usually is hitting the refresh button and the page loads instantly. I was hoping this issue would just go away, but it's been persistent after numerous restarts of our cable modem and switching from wireless to plugged in and so forth. And it's really only happening for our site and no others, which is just puzzling.
At our office on our DSL connection our site loads fine and we haven't had any customer complaints about the site loading slow like this. Our traffic numbers have stayed steady so I don't think it's a global problem connecting with our site. At home I conduct a trace route and it looks good:

Does anyone know what the heck is going on and how I can fix this?
i am trying to optimize my dedicated server to host one website (php-nuke platnuam 7.6v2b5 taking 1min to 1min 30secs to load). ive read the tutorials and it does not seem to make a difference no matter what i try. if one of you guys could kindly point out what could possibly be the problem i would be very greatful.
I have a VPS over at futurehosting, and I'm having some issues with my PHP/MySQL sites loading slowly after a few days of uptime. A restart of the various services (apache/mysql) fixes the issue, but I'd like the issue to not start in the first place.
I know very little of server administration (I'm still learning) so just let me know what info you need to see to do the troubleshooting and I'll get it to you.
I've installed apache on my windows 2008 vps . It's run and when I browse localhost , it's works fine . But when I enter the vps ip address , it says Chrome could not connect to ... , I'm sure that httpd is running on port 80 (I checked it via netstat -ao and task manage ) ....
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?
If I type google.com in my address bar, it forwards me to www.google.com. This is not happening for my website right now. I think its a good idea to do this, since then search engines will have only 1 main URL for the website to index.
My question is:
How do I implement this? I think this may involve mucking with CNAME settings...
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 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.
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 188.8.131.52-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.
