I had serious disk throughput issues that were IMHO caused by the file
system driver (reiser) being too CPU-intensive. This also leads to
buffer overruns, since the writer cant keep up with the incoming data.
Things were better on kernel 2.4 and definitely improved on 2.6 after
re-formatting the file system. (fragmentation)
In light cases, playback is jerky while cutting, in severe cases, even
two parallel recordings caused an CPU overload of my C3-600.
