Hi, I've got a FreeBSD 7.2 box (HP C-class Blade - AMD dual core Opteron (x64), 4GB RAM, Broadcom NetXtreme II BCM5706) that should be connected to a NetApp 3170 filer via NFS. Out of the box, with nothing tuned (no special parameters for mount_nfs, no kernel tuning), performance is very sluggish: I've got ~250Mbit/sec performance with peaks around 400Mbit/sec. Sure enough, neither CPU (server and NetApp) nor network performance is the problem here - it must be something NFS-related. Any ideas on how to increas my NFS-performance? (Special mount parameters, kernel tuning,...) Thanks in advance for any clue, -ewald
