Thanks.
We're testing over the weekend with tcp_rmem and tcp_wmem maxima increased
to 8MB. I got a small apparent improvement on a single node lam-mpi test,
on a machine with a "pro/100" equivalent chip set. The test cluster has
gigabit, as well as Infiniband cards.
Just spent a while replacing all CPUs on the cluster with faster ones,
while learning how to straighten CPU pins bent in shipping.
