Perhaps there's some strange MTU problem? Or a buffer in the NFS
implementation that doesn't work correctly (in both cases, only
directories with lots of files are problematic, but the cutoff point is
likely very different)?
You'll have to wait for someone with actual clue to work at a true
solution, though.
You could always try NFS/CIFS-exporting the disk from the OpenBSD box,
but I'm not sure that would do what you want.
