Extremly high server load

[onel0ve]

Ok i tried changing plugins folder name, but deactivating all plugins didn't worked. This is very weird situation, i mean from the momenth i restore the site server goes on 200 load in a minute and number of processes goes to 400 and more.

A proper server optimization may can reduce you load . As you said you have 4k/day visitor its nt so much . We host upto 8k/day visitor in our shared server with low load , so if you optimized your server then you will nt face any high load problem.

You can use nginx as proxy webserver for your server. It reduces load. A suggested by onel0ve, try to optimize the server if you dont know how contact your provider or hire system admin.

Ok update on problem, changing to default WordPress theme reduce the extreme load. So now the question is what can cause that much load in theme files?

Edit: All plugins are deactivated.

what theme is it ?

[First-Dragon]

It is WordPress premium theme Precisio Pro.

You can use top -c command. It will show you PID of the process taking high load. Using PID you can trace the exact file that uses the load. lsof -p PID
If the theme itself was causing load, then I would guess it was not properly coded and had a bug.

The thing is when i activate the theme index.php process starts to multiple until it crashes the server, causing extreme load very quick. But the theme worked a long time without this problems, and i didn't change any code recently.

Another interesting thing is i have installed another site on same server and when i do performance benchmark using the ab command it gives me totally different results for sites. The problematic one is doing only 0,3 requests per second and other site over 200 requests per second, how is this possible?
