I have a bad experience restoring a vdump backup on Tru64 5.1B + PK4.
Tape is SDLT 320, fibre attached.

The vdump saves datafiles of Oracle 9i (about 300 GB of big files). The full
vdump takes 45 minutes (aprox).

Today I had to restore a single datafile from the tape and it took me 90
minutes !!!

Command: vrestore -i -f /dev/tape/tape0_d1

The system was plenty of free CPU & memory (ES47)

Can I consider this elapsed time as "normal" ??

Have you the same experience ??

I guess that if I restore the full tape, the speed will be much better.
