Can you share the details of the tape marker setting?

We are averaging about 11/1 with data domain on a mix of data. One thing
we found was the need to update a setting for tsm tape marker parameter,
which almost doubled our performance.

We just tested a DataDomain machine with TSM. The results were not as
good as we expected. It shows a very good compression with database
backups (Exchange backups should also work well) but not with normal
user data, like homedirectories or web data.
