100%CPU probleme with my wordpress website

What does “top” show? Is the activity from the database server, web server, PHP process? Note that on Linux, 100% CPU using is not a bad thing as long as the queue length stays reasonable.

I have look in ssh and its looks like HTTPD use 750% of my CPU.
Its worked perfectly on my other site ans i have do a migration with all in one wp after that my website turn very slow, but my other site with the same content is perfectly fast and dont take 100 cpu .

Try playing with the settings for (and possibly disabling for a test) W3Total Cache. It does not look like W3 is aggregating CSS files, which generates more http requests.

Yes, I have already disable W3total cache but nothing to do always my 100% CPU

I like using Autoptimize to reduce httpd activity.

Okay im gonna try it, so i keep W3 cache or i just take optimize ?

For purposes of testing, disable W3 and install autoptimize.

If that doesn’t help, I’d look into your httpd settings.

Okay thank you !

Hey, still the same problem…

If this happens with all plugins disabled and using one of the default twenty* themes, then I think you have a configuration issue on your instance and should look for help with the EC2 support forums on AWS.

They said too me its the HTTPD the problem and i have to see with worpdress…

The place to start looking at what’s going on with httpd is to look at its logs.

Can you tell me how to do that please

They should be in /var/log/httpd. Do you know how to do sysadmin on Linux?

No i don’t im using FTP and putty for SSH
