It helped more than I had hoped:

$ /usr/bin/time -a fc-match foo > /dev/null
0.02user 0.00system 0:00.08elapsed 39%CPU (0avgtext+0avgdata 0maxresident)k
0inputs+0outputs (0major+636minor)pagefaults 0swaps

The key numbers here are 0.02 seconds of CPU time and 636 *minor* page
faults. I believe the latter indicates that all of the pages needed for
the caches were already in memory.

It is nice to no longer be responsible for huge wastage of memory and
CPU time.
