I normally use rsync's -z option to enable compression when transferring files over the internet. However, if I am on my own (idle) gigabit LAN, do I still want compression? Or will it be faster without it? What factors does this depend on? (I haven't done any benchmarks yet).
So basically, is it faster to: compress + transfer + decompress, or just transfer uncompressed?
If your network connection is slow, it's obviously better to compress... but how about if everything is running on a gigabit ethernet network?
