HP-UX 10 means that the machine is quite old. It is not surprising that the
machine has problems performing as expected. I suspect that the performance
measurement tools does not do any processing on the data that is written to
the tape drive.

I would not be surprised if the machine runs out of CPU resource (despite
sar, etc saying otherwise).
