Yeah, I'm not talking about microbenchmarks -- my actual projects tend to
run about 10% slower in 1.2.

Just to give you one concrete example that you can try on your machine, to
see if you get the same results as I:
(use 'clojure.contrib.combinatorics)
(time (dorun (permutations (range 10))))
or
(time (dorun (permutations (range 11))))

I see a 10% slowdown on this function moving to 1.2 (both running under java
-server -Xmx1500m, sampled several times), just like I see on all the code I
have tested so far.
