--- Comment #27 from Luboš Luňák <l.lunak at collabora.com> ---
That said, looking at the profiling of the comment #25 code, the majority of
time spent there is not spent actually uppercasing the string, it's spent in
lock contention and the i18n classes repeatedly updating their internal state.
Without that, it seems the performance would be about the same. So the reason
why the SharedStringPool version is faster is because our i18n code is dumb (at
least as far as performance goes) and usage of libcuckoo removes these problems
from SharedStringPool, not because using SharedStringPool be inherently faster
here.

But I don't think I'll have the time to try to redesign the i18n code or look
into why ValidQuery() gets called so often.
