All of my Linux servers, most of which are Ubuntu 8.04, use "rsync", not 
"rsyncd", since they already run SSH.  They don't suffer from any of the 
problems you've described.

Data throughput is rarely above 10 mbyte/sec, however.  This is rsync, and 
it's not just pushing data.  It is comparing and then sending.  Only a backup 
of a single large file should push anywhere near Ethernet maximum.

I have found that my backup server can comfortably support 4 or 5 simultaneous 
backups, each of which will push at least 5 mbyte/sec.
