The PFSTATSHW_GFXPIPE_BTLNCK token should not have been in the man
page - This is a documentation bug in 1.2. This token will also not
be supported in 2.0. Still looking to the future....

However, for an example of how to benchmark your application
and some different uses of statistices, look at the
        stats.c and bench.c
programs in
        /usr/src/Performer/src/sample/pguide/libpf/progs/

The hope is to one day tell you at least what is the overwhelming
bottleneck of your database, and at best tell you this information
for different parts of your database. Imagine a mode like the
fill statistics where your scene can be painted by bottleneck.....
However, not yet.

Glad for your interest!
