Site Loading Very Very Slow; Help Finding the Culprit

Hello everyone. My site is hosted on a dedicated server; but the site is very very slow. Sometimes it won't even load. In control panel, it shows 100% CPU usage but how is that possible; i mean i got very few visitors on my site. I wanna know how can i find the culprit that is making my site load very very slow. I have a shell access to my site too; but i don't know how to use it.
Thank you in advance.

 

Do you have latest versions of the softwares ? Are your services optimized ? Also a memory leak may be there...100% CPU usage? Something is surely broken!

 

something is probably broken,check which commands/files using most cpu and also dont forget to check ps aux -e output.

 

Hi rootbinbash, that's exactly what I wanted to do. Can you please tell me how to do that? I got Interworx-CP; i got shell access too but don't know how to use it yet. Thank you.

 

Check and optimize your httpd conf , that would definitely help

 

download putty (google putty download, go to the first result) write the ip there and push the connect.login with user root and just write ps aux -e and hit enter.Also check the top(command top,just write top and hit enter) output.

 

Most probably you have something like the infinite cycle somewhere in your PHP code thus you should check the code which you have placed on the site just prior to this CPU usage surge.

 

Yeah I thought that too; but after looking back I don't think i added anything to the site. It is really strange this CPU surge happened out of a blue. It came with no warning . Seriously, i need help. Thanks.

 

as rootbinbash mentioned, download putty, login as root to your server and run the ps and top commands

paste the results in here (highlighting text in putty will copy it to the clipboard) if you want further assistance, but we really need those commands run to see whats happening

 

Thank you. I will paste it down here. I wonder if memory leak is happening; if that's so how do i fix it?

Apache is loading your CPU but is not consuming extra memory, thus I should repeat my advice to check for the infinite cycles, they may be not in the PHP code but in the .htaccess files using instructions which are causing the mod_rewrite or some other part of the Apache to cycle infinitely, or yet somewhere else but related to the web server.

 

i check my .htaccess and it looks same as it was before when everything was nice and smooth. good old days . What or where else can be the problem?

 

Edit:

put an extra 512 ram to the server,it will fix the problem probably.also run the httpd as nobody not apache.

Please paste the ps aux -e output

 

I got this after inserting ps aux -e output:

please edit your post (ps aux -e one) for security purposes (delete the output and say something)

i dont see mysqld running?are your sites/scripts using sql?

 

for a start, an extra 512mb ram will help you alot, as you are swapping quite a fair bit to disk
secondly, certain apache processes are using alot of cpu usage, are you certain you havent changed any scripts recently?
and have you ever optimised your httpd.conf at all to suit your server configuration?

does the load drop when you restart apache? ('service httpd restart')
then run 'top' afterwards to see the load

 

sorry, i didn't understand this part.

yeah i think it uses sql
