--- Comment #2 from Kyle Evans <kevans@freebsd.org> ---
Now that's odd- the difference between these two is that -HEAD defaults to
WITHOUT_BSD_GREP_FASTMATCH (TRE). In all of my testing on three or four amd=
64
boxes, performance difference between the two never differed more than ~4%.

What kind of performance do you get on the -HEAD box if you flip
BSD_GREP_FASTMATCH back on? With that kind of discrepancy, it might be worth
fixing up TRE after all.
