We need more info to say.
How many plugins do you have installed and how big is your site? As labrocca said, we really need a lot more information.
what plugins you installed ?
daily how much impression you serve ?
whats your server config ?
I have 27 plugins installed .. should i remove some ??
Yes. Remove all unneeded one.
bro should i enable the GZIP compression option to lessen cpu usage ??
Gzip compression will likely increase CPU usage by at least a little. Please post your URL.
