I'm having a similar issue that backuppc rsync runs are very slow after the upgrade to squeeze. I've tried a few things: * swapped the network cable and port on the switch (from a wall socket). * removing block sizes on rsync transfer * tried sysctl tweaks in this post: http://ubuntuforums.org/showthread.php?t=891695 * new kernel 3.2 from squeeze-backports (to see if it's a network card driver)* * transferring to a new empty partition and new filesystem (btrfs) I can manually rsync any server (e.g. my workstation in another building) and get upwards of 5mbits (network negotiated at 100Mb) but if I "du -s" a directory being transferred to (e.g a local server on same switch) by backuppc it doesn't increase by more than a few 100k each second. There might be compression/hardlink satisfying the transfer but I'd still expect the directory to grow faster than that. Not so sure will work but is tempting: * upgrade to wheezy The version of backuppc is newer in wheezy but might make it unstable so would rather work out what's up with squeeze. I'm stumped. I "feels" like it's something to do with the way rsync is running. Has anyone had any experience to suggest what might have changed in the upgrade? Any advice very much welcome.
