Try switching to TCP NFS.a 100MBit interface cannot keep up with a 1GBit interface in a bridge configuration. Therefore, in the long run, at full-bore you'd expect to drop 9 out of every 10 ethernet frames. MTU is 1500 therefore 1K works (it fits in one frame), 2K doesn't (your NFS transactions are split across frames, one of which will almost certainly be dropped, it's UDP so the loss of one frame invalidates the whole transaction). This is the same reason you can't use UDP with a block size greater than MTU to use NFS over your DSL or some such arrangement. Incidentially, this has nothing to do with FreeBSD. So if using TCP mounts solves your problem, don't expect Solaris NFS to magically make the UDP case work...
The thing is that UDP NFS has been working for us for years. A big part of our work is performance analysis, so to change our network architecture will invalidate a large part of our data.
