What should I be testing, then? Switching to ADE yields the very same results (except for a different count, of course ;p), FWIW.
EDIT: Same thing for every algorithm in that combobox (in fact, APNX might possibly be the slowest of the bunch, by a very thin margin). Use ICU is checked at all times.
As I said, that's a source build on a source distribution, so things might very well vary on a binary install
