Slow LTO5 tape replication speed

Hi,
We are currently evaluating Acronis for our next backup solution, however we experience real slow speed ~10MB/sec to 15MB/sec maximum on replicating to a LTO5 tape unit.
On the same server we had better/optimal speed with another backup solution, so it's not a hardware problem.
Our tape unit is : Quantum Ultrium 5 SCSI Sequential Device
Is there anything we can do ?
Regards,

Hi,
I'm using version 11.7. However this does not seem to have worked..
I tried creating 'TapeLocation' key and adding the following keys (and tried different values) :
- DefaultBlockSize (DWORD)
- WriteCacheSize (DWORD)
But I get very slow speed... :
[ INFO ] Rewinding tape.
[ INFO ] Trying to perform fast erase of tape.
[ INFO ] Rewinding tape.
[ INFO ] Writing data with block size 16k
[ INFO ] Bytes written: 1G
[ INFO ] Average speed: 3.58042M/sec
[ INFO ] Rewinding tape.
[ INFO ] Reading data.
[ INFO ] Read speed: 20.0784M/sec
[ INFO ] Rewinding tape.
[ INFO ] Trying to perform fast erase of tape.
[ INFO ] Rewinding tape.
[ INFO ] Writing data with block size 64k
[ INFO ] Bytes written: 1G
[ INFO ] Average speed: 7.87692M/sec
[ INFO ] Rewinding tape.
[ INFO ] Reading data.
[ INFO ] Read speed: 17.0667M/sec
[ INFO ] Rewinding tape.
[ INFO ] Trying to perform fast erase of tape.
[ INFO ] Rewinding tape.
I don't think Acronis get the values I put in registry.
Any thoughts ?
