scp stalling

[Bob Ababurko]

Hello-

I have two boxes that I am trying to transfer files between and for some reasson I am getting annoting slow transfers.  I am running OpenSSH_3.8.1p1on the server end with freeBSD 5.3 and OpenSSH_3.5p1 with freeBSD 4.9 on the client end.  The connection keeps stalling and I am not seeing any errors in /var/log/messages.  The only sign is my loss of hair. 

How can I go about troubleshooting this?  I have full control over these boxen, so I can do whatever to fix this.

thanks,
Bob
