Solaris Gigabit Performance tweaking

[Vincent Vallee]

I am currently running rsync 2.5.6 on solaris 8.
I am updating a rather large directory tree including some ISAM
databases and am having some performance problems.
We are using gigabit interfaces between two V280R servers and I am
trying to push the tree with the following options.
usr/local/bin/rsync --quiet --recursive --times --perms --links
--delete-excluded --password-file=/mydir/.rsync_password /localdir/*
rsync://user@server2/remotemodule/
I only get
wrote 11762339 bytes read 2527963 bytes 82364.85 bytes/sec
total size is 6479930905 speedup is 453.45
Is there a way (without using ssh) that I can improve performance?
compression did not seem to help.
thanks
