Having said that, operations that use your network card heavily will always bring your computer to its knees. See "Broadcast storm" for a great way to DoS someone.
I am using N, 10.6, and know what a broadcast storm is. Its not the computer that is coming to its knees its the network. If there is only 1k to back up (and yes thats a little k) i have the same network saturation issue as if there is 10GB to back up. I just think the network shouldn't come to its knees for all computers attached to the time capsule while 1 MacBook over wireless is backing up.
Being in IT for over 10 years I've done a few network backups and didn't run into network issues like this on a switched network.
