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.
