My site just has started to go slow...
 

so I want to find out the problem. how would i start? i have a dedicated server. i know i need to check some logs somewhere......or maybe something else....but how would i start troubleshooting this problem?

so far all i did was restarted the server. but i know thats not the way this problem should be fixed.

thx.

you first need to ask your host if there is problems with the installations.

then you ask if they can evaluate your activities in the last days to see what is the cause... they can read a lot of things you could not understand basically...

best place to ask is over at vbulletin.com in their server optimization request forum, they'll get you taken care of

Start by running "top" and trying to spot anything unusual.

Then take a look in /tmp, again looking for anything unusual, then clear it out.

Go through the logs in /var/log and try to spot any issues.

Those are 3 simple steps, there are plenty more.
