You mean 30MB/s.

I get 20 to 35MB/s for full backups with LTO2 from a raid5 array to a
LTO2 autochanger that is not on the same machine as the raid.

It looks like you have an LTO3 changer by the 75MB/s since that is a
little low for LTO4 however you named the drive LTO4Driver so I assume
its LTO4. I would expect despools of 100MB/s to 120MB/s for LTO4.

I would first look to optimize your filesystem performance as this
appears to be where the problem is. Is your spooling drive the same as
your source data drive? That would kill performance.
