The latest NFS_ALL patches include experimental code that changes the
UDP congestion control. I'm basically trying to relax the algorithm to
what is standard on *BSD (i.e. we follow the standard Van Jacobson).
This would mean that we don't wait for the reply from the server
before we send off the next request. Unfortunately, there appears to
be a lot of setups out there that start to drop packets when this
occurs, and I haven't yet finished determining the root cause.
If I can manage to get my laptop to work again, I'll try to
investigate a bit more this weekend...
Cheers,
Trond
