I usually don't like setting fixed block sizes, but letting Bacula
determine. But Maximum Block Size = 1 MB or even a little bit more
should be safe for LTO-9.

You can use the btape speed test to verify the best values.
The File Size also exerts a role in performance, a trade-off if I
remember well between backup and restore speeds.
Hmm, I ended up with Maximum Block Size = 262144 for my LTO-6, which is
FC, YMMV using another connect.
