        A most stupid one. cvs pserver is making heavy use of
temporary files (in /tmp by default). 10 simultaneous pservers manage
to generate ~2MB/s of continuous write. That had a big impact on
performances (IDE disks). Moving these temporary files (-T) to a
ramdisk reduced IO to nothing and the machine is now operating under a
normal load. It took me a few days to figure out what was going
on. I'm not aware of any tool that would tell you which process is
using lots of IO.

        address@hidden is the appropriate address. The
notifications you sent were not answered (at least not by me) because
I'm not reliable, not because it was not sent at the proper address. 

        Cheers,
