The tar will compress anyway so that's likely to have little if any impact 
(you will probably get better performance by disabling compression in ssh).

Unless you have a very fast pipe and very slow CPUs then one extra 
symmetric encryption is not likely to be a bottleneck (eg, raw arcfour 
runs at ~45 MByte/sec on a P2/400), and the load is distributed on the 
clients anyway.

     Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
