The lookups themselves almost certainly aren't actually taking the
time, unless you have some kind of crazy hash collision happening,
which is so statistically unlikely that it would have to have come
from malice. What's the code doing? What are you trying to accomplish?
It's much more likely that you have an algorithmic flaw than a data
type inefficiency.
