18 simultaneous streams (client-side push using bpbackup with a filelist).
Using 10 streams took a bit longer so fewer streams does not increase
performance.

Are you using multi-streams in the backups to disk? That can cause the
disk to thrash and slow things down.

Any suggestions for increasing the performace of backups to a disk
storage
unit?

I've recently switched a backup from tape to disk and experienced a ~20%
increase in backup times.  Any disk-specific tunables you're aware of?
