Aaaand months and months after I said I'd try it, I finally did. This thing is fantastic :)

Before, with GNU findutils: 40 mins to build the locatedb, 10 mins if everything was in cache. Afterwards (hot cache figures only): 56 seconds. DBs about five times smaller. As for times:

% /usr/bin/time locate wombat
[...]
8.09user 0.08system 0:08.25elapsed 99%CPU (0avgtext+0avgdata 2084maxresident)k

% /usr/bin/time locate -r wombat
[...]
19.75user 0.40system 0:20.38elapsed 98%CPU (0avgtext+0avgdata 2196maxresident)k

% /usr/bin/time locate -r womb.t
[...]
24.98user 0.03system 0:25.08elapsed 99%CPU (0avgtext+0avgdata 2184maxresident)k

Afterwards:
% /usr/bin/time locate wombat
[...]
0.00user 0.00system 0:00.02elapsed 71%CPU (0avgtext+0avgdata 4140maxresident)k

% /usr/bin/time locate -r wombat
[...]
4.95user 0.10system 0:01.68elapsed 299%CPU (0avgtext+0avgdata 10952maxresident)k

% /usr/bin/time locate -r womb.t
[...]
5.15user 0.06system 0:01.72elapsed 302%CPU (0avgtext+0avgdata 11012maxresident)k

This is with a LOCATE_PATH with 19 databases in it, so I think we can safely say that the 20-fold increases in plocate time implied by this are... well... still pretty insignificant :)
