EMACS increase TRAMp speed

Question

after updating to Aquamacs (EMACS 24.4.1) the speed for copying files from remote to local with TRAMP really went down. Of course I know that TRAMP is not really fast for that, but it didn't used to be so sluggish (takes minutes to copy 5MB to local). I've tried setting tramp-default-method to scp snd ssh but no big difference for me...

Any suggestions of how to increase the TRAMP speed are very welcome.

Also I was wondering if the encode/decode base64 is really necessary for copying files and if not how to switch it off.

Cheers, F

Tramp's traces include timestamps. You might set tramp-verbose to 6, and rerun your tests with the different Tramp (Emacs) versions. This might show, where the time is eaten.

If you don't want to publish the traces publicly, send them to me; I could check.
