Platform specific CPU optimisation

[videoaudio]

Hello,

Is CEF and chrome can be built with any platform specific optimisations to reduce the CPU spike when it starts?
I am using cef (Branch 2454) in offscreen rendering mode on platform: Ubuntu 12.04, 64Bit.
When my cef app starts, render process takes almost 40% of CPU on my machine. But as soon Html page, JS load completes CPU usage goes down to very minimum (nearly ~2%). We can simulate this with loading http://www.google.com

I am building cef using https://bitbucket.org/chromiumembedded/ ... ndBuilding and using the release build of libcef.so in my cef app.

Is there any guidelines where I can build chrome with more platform specific optimisations to reduce cpu usage?

Thanks in advance.
