It depends on what you're benchmarking. If the loop time ... is
on the order of the same size as the standard deviation, then it can
fool you into falsely concluding that there's
chunk of the CPU time:

From a practical standpoint I guess it means that deftype is the way
to go if you want fast numbers today.
In this case even the immutable deftype was faster than mutable Java
arrays, so you can
operations are done internally in a single
mutable deftype instance, but it is still very good - in this scenario
there was close to zero overhead from using Clojure.
