I noticed a strange reduction in backup rate, anyone got any idea's:

I have four sessions backing up to one drive (AIT3) with a resonable
backup rate, I've seen between 10MB/S and 24MB/s. When a fifth session
starts backing up to a second AIT3 drive the total backup rate drops to
approx 3MB/s total for both drives.

I don't imagine this is a bottleneck with the server or SCSI card etc.

The jukebox has four drives in it and it appears to happen across any
two drives. At present they are all on the same SCSI channel. Networker
issue ?, it's version 7.0.

Thanks
Nick
