Why would you assume that tuning parameters for one OS and hardware
platform were correct for a different OS on a different hardware
platform?

And the odds are reasonable that the master's parameters weren't
well-chosen in the first place.

Suggest
a) apply the Linux parameter information from a later posting (Lightner)
b) remove the touch files and let the defaults get backups working
c) if you're not satisfied with the backup AND RESTORE performance with
the defaults, read the Backup Planning and Performance Tuning Guide and
tune your media server properly.  OPPs (Other Peoples' Parameters, not
the Canadian version), derived with unknown methodology on likely
different software, different hardware and different configurations,
have even less value than your Sol9 box's parameters.
