SuperDuper incredibly slow.

[echeng]

SuperDuper has been incredibly slow during networked backups for me as well.

With Firewire800, I'm getting over 30MB/s. With USB 2.0, I get 15MB/s. But over gigabit ethernet, I'm getting just over 2MB/s, which is nearly impossible to deal with.

Another thread said that switching to AFP over SMB would make the backup faster, but I switched to AFP and now I'm getting less than 2MB/s -- even slower than when using AFP.

I'm backup up to an Infrant ReadyNAS NV.

Any tips to get networked transfer speeds up to a useful speed?

Doing a finder cppy directly to the box over gigabit yields 30+ MB/s speeds.
