server fps - ljstats issue

Hi
I run a dedicated linux (centos 5.3) box for some cs servers, the config is as follows:
2x Intel(R) Xeon(TM) CPU 3.20GHz
ram/hdd bla bla
kernel 2.6.26.8-rt16 (as u can see its using rt patches)
i start my server with pingboost 3, sys_ticrate 2000,
i use idlers and cron'ed prioritizer, and 99% of the time the server fps is stable at 1000.
this is the list of the plugins i have running:
