What could I do to > diagnose root cause of this problem? You should be able to force it to 100baseT on a GigE switch as a first = step to tracking this down. Are you connecting to a 100baseT hub or = switch? I've had stutter issues with my 100baseT hub so I've switched to = using the GigE switch entirely... I also switched my board from octm to = octe interfaces for things like NFS, on the theory they are better = optimized... I've been away at BSDcan for about a week, and so my experience is about = 10-15 days old right now. Today is catchup day at work, but I'll try to = look to morrow. Warner=
