how to fix excessive latency

[wwanghongrui]

I am sorry for my bad english. My nagios server is not running in virtual server.  Nagios3.2.0 + Suse10-sp2 x86_64 + 8 GB mem + 4 x ( Xeon(R) CPU  E7420  @ 2.13GHz ), I think this hardware is enough.
 "I use vmstate to capture system performance", vmstate is a command in SUSE10,not a virtual server. 

My configuration is like below,I don't know which parameter should I optimize,could you give me suggestions, thanks~

Endeavour to not run Nagios on a virtual server. If you must use a virtual server,
make very sure that your checkresult spooldirectory and status data files are on
a ramdisk, or you will certainly run into trouble.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
