I tried that after I posted, but only saw roughly 30% improvement (which
is consistent with my earlier tests IIRC). Not bad, but this still left
plperl initial call at ~40 msec versus plpgsql at ~4 msec. It is
possible that the initialization function that I used,
plperl_init_all(), doesn't include everything it could. I might play
around with it when I get a few moments.
