Yeah. I've found it to be pretty broken in ot

I have a 2.8GHz Core i7 machine backing up uncompressable data spooled
onto an 8 drive RAID5, to LTO-4 tape.

I have a 2.8GHz Core i7 machine backing up uncompressable data spooled

Our requirements now dictate that data encryption must be used on the
tapes and having configured this, it seems that one core is saturated
encrypting the data and the result is that tap
