I started the first backup to an empty directory on a second server.
...
Everything looks fine:
CPU-usage on the source-server is ca.15% for ssh and ca. 6% for rdiff-backup
CPU-usage on the destination is ca. 18% for sshd and ca. 12% for rdiff-backup
No swap-space is used.
rdiff-backup needs 132s to transfer a 140MB file (1.1MB/s). While
rdiff-backup works on the next file scp transfers the same file in
15s (9.3MB/s)!
Hmm, when other people complained about slow rdiff-backups I thought
the problem was CPU usage but obviously this isn't the problem in your
case.
Try editing your Globals.py file and increasing blocksize and
conn_blocksize by a lot. For instance, try:
blocksize = 524288
conn_bufsize = 1572864
I'd be curious to see if this makes much of a difference.
i will try that when i start the backup in the opposite direction. ETA
for actual run is Thursday.
