Hi,

I have recently upgraded a long term BackupPC server from 2.x to 3.1.0. Now that the admin jobs can run during backups, they start at 01:00 and run many hours. 4 backups are running simultaneously and the load average holds at around 16-17. How is the best way to tune for performance? It is 75-85% waiting on the disk. Maybe this is okay?

top - 08:21:03 up 1 day, 17:56, 1 user, load average: 16.44, 16.68, 16.56
Tasks: 135 total,   2 running, 133 sleeping,   0 stopped,   0 zombie
Cpu(s): 8.4%us, 1.8%sy, 0.0%ni, 0.8%id, 88.4%wa, 0.1%hi, 0.5%si, 0.0%st
Mem:   1035864k total,  1023804k used,    12060k free,    12368k buffers
Swap:  3036244k total,  1136444k used,  1899800k free,   386260k cached

Thanks in advance,

James
