This might be due to overhead in FreeBSD's built-in free(3). Please
try the following patch (for 9.2.4rc4 which is the only version I have
right now, but I beleive it should just apply to 9.2.4.). It enables
an internal wrapper for the build-in functions, avoiding the overhead.

I've often heard this type of problems, but I myself don't have an
environment to reproduce it. So it would be nice if you could tell us
the result, whether positive or negative.
