When i copying /usr/src tree from file server (AMD K6-2 225) to my Duron 1133(1GB RAM), speed is about 3-4MBytes/s. But played music on my PC is some gappy. Also removing /usr/ports tree have same much effect for music. I set large buffers in all avaliable players(mpg123, mpg321, mplayer, xine, xmms) on my system (FBSD6.0-current 1 may 05), but it don't have effect. I think that somthing lock IRQ from sound card(SBLive emu10k1 classic FBSD driver :) ) or call of SB buffer fill. How to diagnose what uninterruptable process(or in system function) can to lock CPU for so much time (1 sound buffer - 4096 bytes 4096/176400=~23ms) ? And, please, help me with tuning of sound performance. I think it depend from disk issues. -- Best regards, Andrey mailto:samspeedu@mail.ru
