That depends on the bottlenecks. If you are CPU bound the
rsync deamon will perform marginally better. That is
because ssh is encrypting the data. Of course that means
that the data will travel in plaintext for anyone to snoop
so if your network is that secure (and switches don't make
it secure) you could use rsh and get the same speedup if

Better control over what may be read or written
Allows anonymous access for public servers.
Can allow individual rsync accounts seperate from
system accounts (security issue).
No encryption burdening the CPU.
Another daemon to make sure is running or launched
Yet another configuration file to write and keep up
Another set of passwords to track.
Passwords stored in plaintext files (security issue).
No encryption protecting a datastream that may
contain confidential information (security issue).
Next time put your questions on seperate lines.
