I have: kern.clockrate: { hz = 4000, tick = 250, profhz = 4000, stathz = 129 } but no difference. Yes, overheads are lower and my application's performance is better but thread switching time is same. AFAIR I have read somewhere on the Internet about such problem when playing multiple video files and the solution was to change some parameters somewhere in header files but I cannot find this again.
