I can't answer this, but whatever algorithm it uses, we're unhappy with
it!

We have a couple of systems where we exclude entire subtrees with very
simple include/exclude statements, yet an incremental backup spends an
inordinate amount of time rummaging around subdirectories where is
cannot possibly have anything useful to do.  For example, one subtree
with 250,000 files in it caused 90+ minutes of client cpu crunching.

So there are at least 2 usability problems here: (1) client cpu usage
and backup duration are inexcusably large because ADSM rummages around
where is has no business, and (2) COMMTIMEOUT and/or IDLETIMEOUT must
be ridiculously high because the server and client are ignorant of
what's going on.

One would think that a simple (internal to the ADSM client) question
such as "Is everything in this subdirectory excluded?" would be a
better performer than simply applying all rules to all files.
