Now I'm running 10-process lighttpd and the problem became no so big.

I collected interrupt stats and it shows no relation beetween 
ionterrupts and slowdowns. Here is it:
http://83.167.98.162/gprof/intr-graph/

Also I have similiar statistics on mutex profiling and it shows there's 
no problem in mutexes. http://83.167.98.162/gprof/mtx-graph/mtxgifnew/

I have no idea what else to check.

With best regards,
Alexey Popov
