Problems with high load

[Matthias Blohm]

Hi,
Specs: rsync is running as root with prio: 0
Linux: Debian Kernel: 2.4.30
Rsync: rsync  version 2.6.4  protocol version 29


We are having problems with a very high load at the time of an rsync is running.
Sometimes if 2 or 3 Rsyncs are running simultanously on to the same machine the load goes up on 
that machine to 10 or more. the datas will be synced in about 2 or 3 minutes with about:
sent 3277383 bytes  received 3719902 bytes  31590.45 bytes/sec
total size is 391067345  speedup is 55.89

But the Load is so high that all the Webserveres are stopping its work.

We have no bandwith throttling because it is important to get its changes fast.

Any suggestions or answers??

Greetings
Matthias
