Just for the record, last night setoff a policy which normally streams 5
jobs to 2 drive.
This time, configured for 3 streams to 3 drives. Just got into work and
found its MUCH SLOWER than the week before !!
So I will revert back !!

If you backup server can handle the incoming IP traffic, and you can get it
to the drives......it will be great.
I found best aggregate performance for LTO2 and LTO3 with my GigE clients @
MPX=2, and my 100Mb/s clients @ MPX=8.

Hi all,
How good/bad are LTO-3 drives when it comes to multiplexing? Would we see
great performance degradation if we set MPX to 4 on 1 LTO-3 drive and the
run 4 simulations backups to that drive?
I understand it can depend a lot on our clients as well...
