I ran mandelbrot.rkt 20 times, and the times are still distributed
bimodally.

I have two more tests that are substantially improved -- fasta (2.5
faster), and reversecompliment (also 2.5x but will probably get to
around 3). Will you submit them?

I'm not sure where to get the mandlebrot-unsafe.rkt that was
distributed with 4.2.5 (Eli?) but so far

Actually, the benchmark on the shootout webpage is named
mandelbrot-unsafe.rkt in the repository. The version I had in mind is
mandelbrot
Perhaps it suggests a bug in the interaction between that fancy
require operator and the optimizer?

I think you missed the require line. It is using unsafe-fl+ for example.

You're right, my mistake.
But that makes it even weirder that when I manually replaced these fl+
with unsafe-fl+, the running times became consistent.

No, it uses fl+ and friends. An unsafe version would use unsafe-fl+
instead.

Why is this? I thought Typed
We're talking about this code, right?

It is already unsafe, I think?

I submitted a request to the computer language shootout to rename PLT
to Racket. The following message shows the difference in performance
between 4.2.5 and 5.0 - it's probably worth taking a look at the
discrepancies.
