Under what configurations, versions, etc.? easy - Fileserver is RAID and/or Lustre and you have a high bandwidth network. This can easily outstrip the IO available from a single local disk This point also crops up when people do ftp (or scp) perfromance tests across their high BW network (like our QsNet). Unfortunately they end up measuring and hence reporting the bandwidth of the disks at either end.:-( Daniel. -------------------------------------------------------------- Dr. Dan Kidger, Quadrics Ltd. daniel.kidger at quadrics.com One Bridewell St., Bristol, BS1 2AA, UK 0117 915 5505 ----------------------- www.quadrics.com --------------------
