I knew these numbers were too good to be true -- it turns out the
stock mod_perl config has such a low Apache::SizeLimit that the
process gets killed after a few requests. I've re-opened and the new
default will be a more more reasonable 250_000.

I'm still keen on benchmarks, and I'll post my revised ones shortly. I
recommend editing and setting the size limit to 250_000 or
or wait for Bug 731589 to land.
