Same here.

MPX=2, and 4 streams (1 per Information Store) to 2 drives has proven to
be the fastest way we can do this.

Actually, almost all windows servers we've tested, with GigE have
required MPX=2 to be able to stream the LTO2 drives.
If the servers has multiple physical disk arrays, we can pull multiple
jobs from the same machine....one per disk array, but no more than two
streams per tape.
