Dedicated server has drops?

[karibo]

Hello,

I've had a dedicated server for almost a month now, but I'm experiencing a weird problem sometimes the websites go really slow, I could also see the pageviews/minute go down from 700-800/minute to 150-200/minute.
Then after 10-15 minutes everything is back to normal for a few hours.
This is weird..
When I was experiencing the problem I pinged my server and did a traceroute, everything seemed fine to me.
Any Idea?

Disable your CPU speed stepping. Force the CPU to stay at the maximum speed possible at all times.

I can't seem to find how to do this. (CentOS 6.3)

Check you memory stats (server using swap?) and the list of processes running plus their cpu & mem usage.
If you're running java app it could also be garbage collector running.

Install cpufreqd

My Dedicated Server knowledge isn't that great, You'll need to tell me where/how I can find the information that you're looking for.

Wordress site(s)? If so, doesn't look like you implement caching. Install w3 total cache or whatever you want to use. Also, next time you see mysql killing your cpu, run the command below and paste results here.

mysqladmin pr stat

The load in your server seems normal, I think you have a problem in the configuration of Apache.
Check and increase "ServerLimit" and "MaxClients" in the apache config file, then restart the server.
Good luck

Does your host offer support for the server? They've probably seen situations like this before and would know how to help.

No, It's a self-managed server.
They only handle the hardware.
