Anyway disabling no_sse2 was a bad idea, increasing jitter/overhead. Some optimizations for low-jitter such as no_defer and prefech latency can change percieved latency/jitter slighty. http://paradoxuncreated.com/Blog/wordpress/?p=4223 And I am always interested in more information on that. Currently I am using "-O3 -fno-defer-pop --param prefetch-latency=100"
