Typically running bigasm against IBM LTO-2 tape drives on Solaris hosts I
have seen a peak speed of around 42MB/s. On the whole, bigasm does generally
represent a nice level of compression without going overboard.

On the second general question of "what speed have you obtained", the best
yet remains an LTO-1 tape drive which ran at around 98MB/s backing up heaps
of holey SQL databases...

Cheers,

Preston.
