Hi,

We experience some trouble when 200+ nodes mount the same NFS
directory, each opening a different file and writing a small number of
bytes to it.  Even though we're not using anywhere near the capacity
of the ethernet card or the disk writing speed, the load average on
the server goes up to above 20 or so, and the system is very slow.
The system is a dual Athlon MP 1800+, but the cpu usage is near 100%,
practically all of which is spent in "system time" (vmstat).  Do you
understand why this is happening, and is there anything we can do
about it?

Thank you
