DragonFly bugs List (threaded) for 2004-07
Re: the new scheduler
:Tried burning a DVD with it earlier, everything was fine and it went
:smooth. But now I've tried to play MP3s with mpg123 and XMMS and it's
:_not_ a smooth experience, mpg123 skips every know and then, changing
:mpg123 niceness screws everything up.
:XMMS is slow, takes some while to change song, impossible to use the
:buttons or move the window after a small while, changing nice value
:makes it stop (maybe it stops without that aswell).
:Anyway, it doesn't work good at all.
: (and in a followup message)
:niceness -10 seem to be ok for mpg123
:using opensound for dragonfly if that helps/matters
:CPU: AMD Athlon(tm) XP 1500+ (1312.94-MHz 686-class CPU)
: Origin = "AuthenticAMD" Id = 0x662 Stepping = 2
: AMD Features=0xc0400000<AMIE,DSP,3DNow!>
Hmm. I have a very similar workstation:
CPU: AMD Athlon(tm) XP (1243.35-MHz 686-class CPU)
Origin = "AuthenticAMD" Id = 0x681 Stepping = 1
mpg123 seems to work fairly well, but I'm just running it on an mp3
file manually. When I first read your report I thought it might be
cpu related but mpg123 seems to actually take very little (only 2% of
the cpu). The scheduler is correctly identifying it as an interactive
program so I suspect that the issue may not be the scheduler at all.
You could experiment a bit with mpg123's '-b' option. If a larger buffer
doesn't solve the problem then it is more then likely that (known)
interrupt latency issues are the cause of the skipping you are hearing.
