TSM Fastback Server has extremely slow read operations from disk

TSM Fastback Server has extremely slow read operations from disk:
- all restore operations with both methods, Fastback Mount and Fastback BMR,
- DR to TSM and
- long term proxy backups to TSM.
The speed of restore does not exceed 10Mbit/s (aggregate) on the system equipped with 2 Gbit NICs in a Team. For example, copying 6 GB big file from a Fastback mounted volume to a local disk takes more than 4 hours.
Backup is doing better, with speeds up to 180Mbit/s, but without dedup it is even better - up to 500Mbit/s . The repository is a dedup volume on SAN disks.
All read operations are working slow and the DR is not working at all, because the system cannot transfer the files in the "free" timeframe, thus dedup is not useful, because you cannot wait for a system to restore more than one day.

    Thank you for submitting this request and we apologize for a delay in our response. Unfortunately, at this time we cannot commit to delivery of this enhancement in the next release or two. As an alternative approach, you may want to consider TSM server and Cristie BMR solutions to provide better performance than you were experiencing at the time you submitted this request. If, after our next release of TSM, you would like this requirement to be re-considered, please resubmit the RFE. Thank you for your commitment to TSM and for your support in moving the product forward.
