Hello Ryan,
1) Raid5X is going to kill your performance. As mentioned in a previous
message, convert to RAID10 if you can afford the space decrease.
The write speed of RAID 50 is higher than RAID 5 and i think this is not the
problem on my system. The backuppc server input - reading from
What filesystem are you using?
The standard filesystem of ubuntu 9.10 = EXT4

I don't see an urgent reason to migrate to 64 bit... I would have
installed this machine 64 bit at the beginning, just because it's a 64
bit machine.

Hello Tino,
Your I/O system seems saturated (70-80% of time is spent waiting for
I/O). Try running only one BackupPC_nightly in parallel.
Yesterday i set $Conf{MaxBackupPCNightlyJobs} = 2; to
$Conf{MaxBackupPCNightlyJobs} = 1;

Hello Gerald,
Is this running in a VM? I often see high CPU wait times when doing disk
I/O in a VM.
No, it is a normal system with a hardware raid-controller.

Hello Daniel,

ADAPTEC 3805 RAID SAS/SATA 8−Kanal
Hardware RAID without BBU (and of course, without write-back cache
enabled) is usually *very* slow, much slower than simple disk system, or
software RAID.

If you aren't pressed for disk space you might improve things by

It traverses the pool directory, stat()'ing each inode (which isn't like
to be near the directory) looking for entries that only have one
