hi,
when I use multiple instances of sfread~ and I change the file in one of them I get occasional dropouts (esp. with large [5min stereo 44.1] files, sometimes up to 2 secs) even when there are hardly any other processes (even sys/klogd killed), -rt, lowlat enabled, swap is off.
that's PIII@700Mhz/192Mb
hdparm -Tt says: /dev/hda: Timing buffer-cache reads: 128 MB in 0.83 seconds =154.22 MB/sec Timing buffered disk reads: 64 MB in 4.13 seconds = 15.50 MB/sec
under normal conditions ... I can squeeze out a bit more tuning the settings but the problem persists ...
you guessed it that's on linux (Debian 3.0/ kernel 2.4.16-lowlat)
any hints ?
thanks,
x
