Yes, I'm aware of that :-)

I know that, too. My point is just my system seems fast enought, I can
do 20+ tracks in ardour (which admittedly knows which samples should be
played in advance). And my HD is performing ok:
ajstrup:~# hdparm -t /dev/hda4
/dev/hda4:
Timing buffered disk reads: 122 MB in 3.01 seconds = 40.47 MB/sec
It would be nice if chuck had a way of filling a SndBuf in the
background, it should be finished when it's ready but should cause no
hickups, and an a possibly with an ability to check at any given time if
the reading has been completed.
