Turn off rysnc compression on LAN copy

While copying files over local area network you might consider turning off compression in rsync as it will bottleneck one of the CPUs at either end. In my example below I was copying from a Core i5 @2.3 MacBook Pro to a Core i7 Linux over a 1Gbps connection and I had this results:

$> rsync -av --progress source@ . - average speed 22MB/s
$> rsync -av --compress-level=0 --progress source@ . - average speed 90MB/s

As you can see with compression off I achieved 4x the speed than using default compression.
