[rdiff-backup-users] ssh speed problems

[Andy Wettstein]

Hello,

I am having some speed issues using SSH on FreeBSD I think.  I am 
using rdiff-backup 0.12.7

/home/admin/ajw is NFS shared and is about 200M.

Backup using NFS:
address@hidden /tmp >time rdiff-backup /home/admin/ajw ajw

real    0m35.622s
user    0m6.491s
sys     0m8.195s

Backup using SSH:
address@hidden /tmp >time rdiff-backup --ssh-no-compression 
montrose::/home/admin/ajw ajw
Enter passphrase for key '/home/admin/ajw/.ssh/id_dsa':

real    6m22.974s
user    0m9.342s
sys     0m6.171s

dylan is a xeon 2.4 with SCSI disks running FreeBSD 5.2.1.  montrose is a 
tru64 machine with dual 667 alpha processors and that home directory is 
stored on a fiber channel IDE raid.  These machines are on the same LAN.

This is the result using a tru64 machine to back up the same directory
(500 Mhz dual CPU machine).

NFS:
address@hidden /tmp >time rdiff-backup /home/admin/ajw ajw

real    1m7.271s
user    0m21.949s
sys     0m17.422s

SSH:
address@hidden /tmp >time rdiff-backup --ssh-no-compression 
montrose::/home/admin/ajw ajw
Enter passphrase for key '/home/admin/ajw/.ssh/id_dsa':

real    1m55.916s
user    0m30.931s
sys     0m11.681s

What can I do to speed up the FreeBSD backup?
