        I'm still trying to figure out exactly why 20 CVS pserver
processes can generate such a load average. The vast majority of CVS
pserver processes are simple anoncvs, i.e. read files. I see no reason
for a disk that has 20MB/s of transfert rate to be saturated when
serving less that 200KB/s total (as shown on mrtg graphs). There is
something seriously wrong somewhere ...
