[hunchentoot-devel] serious H'toot performance problem on CCL OSX ?

It looks like there is something inside my
seemingly identical CCL/H'toot that makes it run 1/10 as fast
as Wade's.
For what it is worth, running 'top' during the benchmark shows that
CCL is running at 100%+ CPU, but the 'ab' benchmark tool making
the requests is using almost nothing. Unfortunately, profiling on CCL
is not straightforward, so I can't figure out where the CPU is spending its time.
It's not terribly important for me, because I'll probably run it on a
different platform than a Mac. It's sure irksome and inxplicable.
Thanks to everyone who looked at this.
