I'm running into the same problems myself.  Host machine is NetBSD/i386
1.5_BETA, ffs + async mounting (no softdeps), running on FDDI.  Client
machines are an assortment of NetBSD, Linux, and Irix.  They all
exhibit the same general slow-write performance (reads are really
fast, though).

The filesystem is on a 23gb fast/wide SCSI drive.
