John,

Based on my experience, you're doing fine.

* Your system is doing zero paging to/from disk (pi and po are both zero
consistently);

* Your scan/free ratio (sr/fr) is about 2, which is OK.  Rule of thumb is
sr/fr should be 3 or less.

When my TSM server had only 512 MB, I was able to tune it for zero "po &
pi" and 97+% TSM DB cache hit, but sr/fr was about 16.
