RE: TSM on Linux hosted on i5 outperforms TSM running on i5/os PASE.

Not really.

PASE isn't an interpreter because there isn't anything to interpret.
Remember, the i and p series run on the same hardware.

From the "Fortress Rochester" book:

"PASE uses the processor's ability to switch between AS/400 and RS/6000
mode to execute an application in the PASE runtime. <...> Performance is
equivalent to a comparable pSeries or RS/6000 system running the same
application."

The issue appears to be differences in the device drivers required for
sharing in an OS-400/PASE environment versus a standalone AIX/Linux
environment.

Perhaps Rob could comment, but I imagine that with TSM in PASE, as long
as TSM wasn't using the tape drive OS/400 could use it with nothing
special to do.  Whereas with TSM in a Linux partition, the tape drive
would have to be moved from the Linux partition to the OS/400 before
OS/400 could use it.

Is PASE not a giant interpreter?  Kinda like comparing basic 
interpreter
to compiled basic.  Everything should run faster using native code
compared to interpreted code.
