The bad performance in Irix appears to be a lack of resources, most likely system buffers for sockets and I/O. Try increasing the system parameter, nbuf, using systune, reboot, and see if it helps. Also, use the "par" program with options "-s -SS -i -u -p <pid>" to monitor activity in the backend -- that may provide some clues. +-----------------------------+------------------------------------+ | Robert E.
