I can assure you, it's not compressed (I switch compression off because the line is fast enough but the CPU gets slowed down with compression). And I tried it with FTP. With FTP I'm getting 37 MB/s (almost the maximum what the disks on the other side are able to write) and there's no loss of speed whatsoever the whole time during the transmission. > Barring that, If you aren't concerned about somebody sniffing the content > you're syncing, perhaps you could use the internal transport?

This would be an option, but doing rsh with a root account is not possible (couldn't get it to work, I haven't found any way to do it for root and I really want to do it with the root account because I wanna have the same file, directory and user permissions on the files) and also not quite recommended... (.rhosts ??? Sheer horror ! ;-)) Maybe it is the encryption but I use ssh otherwise too and can get on the same line results upto 12 MB/s (blowfish) and even 20 MB/s (arcfour) without any loss of speed. The funny thing is, it seems to happen only after a short while. The first 5 minutes seem to be going good, almost 18 MB/s (also arcfour which means, this is very similar) and then it goes down. It never goes up again, even when a new file get transferred, but it starts at 18 MB/s when I start the complete rsync again. BTW, if it wouldn't be for the deleting feature I could also use dmscp. dmscp is a neat tool which uses ssh authentication but don't encrypt the data so it's fast enough like FTP etc. Maybe there's a similar tool outside with the deletion feature ?
