It seems that way, yes. I do not know how common the holdoffs are in real

from reiserfs to ext2/ext3 actually made a difference - this would tell us
that it is indeed a real-world problem.
This was not a synthetic benchmark, I would consider this a 'real-world'
problem now. Repeating the test with ext3 would just tell you whether
it has the same problem.
If it is neccesary to get the reiserfs issue addressed, I will repeat
the test with an ext3 system in the next few days, I would like to hear
from reiser on this before doing much more.
resierfs: yes, it's a problem. I
"fixed" it multiple times in 2.4, but the
fixes ended up breaking the fs in subtle ways and I eventually gave up.
andrew, this is really helpful. should we conclude that until some
announcement from reiser that they have addressed this, the reiserfs
should be avoided on low latency systems?
Note that this info because available because someone
set
/proc/asound/*/*/xrun_debug. We need more people doing that.

This goes back to the need for ALSA documentation. Someone needs to
write some. This will probably require paying that person. Hopefully
SuSe is working on this, though I suspect I would have heard something.
