I am currently hosting my website on one server with the specs:
2.8ghz Dual Quad-Core processor + 8 gigs of ram + two 500 hard drives with a 50 mbps unmetered bandwidth package.
My current problem lies in high server loads and very slow server performance throughout the day.
I am considering migrating over to The Planet onto server with the specs:
3.0ghz Dual Quad-Core + 18 gigs of ram + two 50gb hard drives with 2TB of monthly bandwidth transfer.
In an attempt to have great bandwidth pricing and server performance, I plan on downgrading my current server with my current host to a lowe-end server and keeping it only to host my VIDEO and MUSIC files with the 50mbps unmetered package. The Planet will then host my database and all other web related files on their new server.
Is this a good idea as an attempt to save money in bandwidth costs and eliminating my server lag issues?
I was offered a setup of a separate web and database server at my current host but from what I have read, no one touches the performance and reliability The Planet has to offer.
I recently started hosting a large vBulletin forum (14,014 registered users... 30-60 online at a time) on one of my dedicated servers. When there's a lot of activity on the forums, things start getting really slow. There will be like 50 php-cgi processes running. Some users get blank pages, others get this message:
Notice: Undefined variable: errfile in [path]/forums/includes/functions_log_error.php on line 163
Specs of the server are: AMD Athlon 64 3000+ 160GB SATA HDD 2GB DDR2 RAM FreeBSD 6.2 (Hosted at AwkNet)
Could there be any Apache modifications I can make to increase performance, or anything else I could try?
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.
I have a site that is eating up my server resources and need to know what the best solution for this is. I'm thinking of getting another server just for mysql but do not know what specs the server should be to handle the current traffic/database load and have the site run smoothly without slowing down to a snail's pace.
An alternative is to get another server just for the videos being served and leave the database and html on the current server. This is where I'm stuck and don't know what route to take with this.
I've attached screenshots of top and bandwidth usage per day. Hopefully with this information you could tell me if I need another server or if there are any things I can do to the current server to help things move faster.
I dont know much about what could be cuasing this so i come to you for advice, i am currently at wired tree on their VPS384 package with 348MB of ram and my site is really slow to load [url]sometimes it is so embaressing to show people i just dont bother, i am sure this is deferring visitors from my content how can i speed this up?
I can add more ram but it will push the price and if the price goes too high i might aswell move to a Hybrid with wiredtree.
My server gets 300 - 600 concurrent connections to http port 80, has a CPU load of 1 - 2%, has practically all RAM of 1 GB used, is running apache 2 and centos 5.
It tends to get slow and when I ban IPs that use many connections to my server (raping it), it becomes fast again. But soon after that new ******* users come which I again ban and the process repeats itself
I'm starting to think that maybe I just don't have enough RAM to handle them because it seems at least some of those users are legit. I don't however have even that much content that needs to be cached so I'm not sure what good RAM would do but perhaps apache just needs more.
My server has a small load (about 30% of it is being used) and it is still running very slow. When I reboot it runs fast for about 5-10 min, and then it is back to slow. I reported this to hivelocity and the responded with " The problem was one of your apache process was pegged out. Restarting apache resolved this issue. If you still have issues check top and run lsof on the process ID that is pegged out."
and after it continued "It will continur to happen until you isolate the source of the issue and stop it.
The load looked fine just now, so I am not seeing an issue.
What you can do is when it pegs out (simply restarting webserver will get it back up but not resolve) run the following command:
Look through the processes to see what is calling it."
Whn I run ps -aux i see a username on my server. i suspended that username but the problem is still happening.

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?
Now-a-days server is having too much load due to http and in access logs we see following message : ======================================== 127.0.0.1 - - [11/Oct/2008:01:40:02 -0700] "OPTIONS * HTTP/1.0" 200 - 127.0.0.1 - - [11/Oct/2008:01:40:03 -0700] "OPTIONS * HTTP/1.0" 200 - 127.0.0.1 - - [11/Oct/2008:01:40:02 -0700] "OPTIONS * HTTP/1.0" 200 -=============================================
And due to this there is load on server. We are not able to understand why this is happening and how to stop this. So please suggest with some solution.
do you know what my server having very strange problem my server load suddenly increas after every 2 or 3 days some time after 1 days but when we talk about those days in which server load is fine then that time server load very low almost 0.4 to 0.1 .
But on that high load day server load reached upto 500.
when i try to find out what wrong then i only get that there is too much connection of http when i kill httpd through this killall -KILL httpd then server load suddenly decrease and then stable.
I've got a server that suddenly over the last three days has exploded as far as server load. Watching top I have some httpd processes that are using up all of the cpu and lasting for quite some time. How can I find out more about these hanging processes? I need to track this down as quickly as possible and find out what the cause is.
if upgrading to that new server that I'll mention will probably solve my problems. Whatever help you can provide would be greatly appreciated. Below are the details:
In the GMT evenings and nights my current server gets so loaded that every page load takes 10 - 30 seconds. Even the pure html pages will be so slow to load. It seems that after a certain treshold it just suddenly becomes that much slower. Not much middleground there. I have high MaxClients and ServerLimit values now and the error log doesn't say that they are exceeded anymore but that didn't help enough.
I have a high traffic website that is using latest version of apache (2.2.x) with the prefork MPM and apache is optimized, PHP 5.2.5 and APC 3.0.15.
I get 160,000 - 210,000 pageloads per day. 32,000 - 45,000 visits per day.
Most of its pages are PHP but shouldn't be too CPU or databes intensive. Mysql isn't used and I mostly used sharedmem (php's shm functions) for databases. 2 semaphores are quite heavily used but that can't explain how a few more users would make the server serve pages so much slower.
Swap usage is practically 0 and CPU user % usage is like 1 - 2 % and CPU system % is also about the same even during peak times. However the Average Load or whatever that "top" reports is 6 - 9.
My current server scecs: 1 GB Ram, Pentium D 3 ghz, CentOS 5 32bit fully updated.
I load all pictures and even the stylesheet from a secondary server by using href="$secondaryserverIP..." in the html code, so the main server practically just serves the pages.
My new server will have apache with the worker MPM and latest versions of every software. Also its specs are: 2 GB of RAM, Intel Dual Core Xeon 2.40GHz, CentOS 5.1 32bit fully updated.
I have a sophisticated netstat based ddos script that is an improved version of DDoS Deflate and while some of these slowdowns seem to have been caused by attacks that it then was able to defend me from, most of them are not. I am even protected from users who constantly have 7+ connections to my site and if someone has a way too high number of connections, the script won't even check if it constantly has it and the script just bans that user outright. It probably is banning a bunch of innocent proxy users too but that is a small price to pay.
Alright we just bought a new customer aboard with a ChatBox on the site it seems as if this chatbox is causing higher load we went from 0.00 to 0.68-1.12 now this happened on our old server before too with another chatbox. They use vBulletin any ideas as to what would be causing this?
MySQL the last few days seems to be constantly the most demanding process in top, which it never was before. As far as I can tell, nothing has substantially changed with regards to traffic to MySQL driven sites on the server. Is there anything that might be wrong with the databases, etc., that might throw MySQL into a tizzy?
I have two quad core processors and load is like 15.
May it be caused by switch if it doesnt let traffic trough properly?
if dmesg grep eth shows 100 full duplex is it normal or should it be 1000 full duplex?
how can I make it 1000 full duplex on centos 5?

So the site got featured on [url]and now the server is drowning...
The Coppermine Gallery usually hovers around 30~50 users daily and now, 1800, and im at a lost as how I should configure mysql to take on such a load. right now it takes about 10 secs or more to load a page and sometimes it would time out. Because it si coppermine, all pages are dynamic and can't be cached -_-"
Here's the my.cnf right now after i played around with the numbers
