I have a 486/33 with an SMC 8013 board running NetBSD on a network with
PC's running SCO and DOS/Lantastic, and HP's running HPUX. I can rlogin,
telnet, ftp, and NFS mount file systems across various combinations
of machines/OS with no problems. However, throughput to and from
NetBSD (and 386BSD) systems is terrible - 2-4K/second. Throughput
to and from other machines is at least 200K/second.

I don't notice any delays with rlogin or telnet. When I ftp and turn on
hash mark printing, I can see several (10-20) packets burst through and
then it just hangs for 5-30 seconds. Eventually, the transfer will finish.
When I try to copy files to/from NFS mounted filesystems, I see the same
pattern with the occasional "server not responding" message.

Has anyone seen this behavior before? Any suggestions for a fix or at
least some pointers as to where to begin debugging?
