If I'm making an image of the entire disk on my laptop and storing the archive on a NAS device via wireless networking, doesn't it make sense to set the compression to the "slowest" aka most compressed setting?
I think the idea that more compression is slower is based on writing to a fast, local hard drive where the CPU doing the compression is the bottleneck. I don't see but about 29% CPU usage on the laptop, probably because the wireless link (it's the "g" not "n" wireless protocol) is such low bandwidth the compression can be easily kept up with.
I haven't done it both ways but a 50GB-ish backup in a little over an hour and a half seems pretty fast.
