Low server FPS - centos

[oo22]

Hello all,

I'm having an issue where my server gets very low server FPS when the server is full. Upon start the server will have 500 fps all the time.. When it fills up then the FPS drop to around 15 - 60.

Now I'm not sure if this is related but i recently update CentOS and noticed a strange change in the context switches (How many times a program is swapped from memory into the processor).. Here's a graph:



Note that the server USED to run fine before the update.. You can see the results of the update because the context switches cap at around 2k when it took place.. before, under heavy load the context switches would go up.. now they go down instead..

If anyone has any ideas to what may be causing this problem I'm all ears!

(Note: This thread looks similar to my problem in some fashion.. except backwards.. http://forums.srcds.com/viewtopic/5973)
