Hi Jared

I wasn´t aware of this easy-at-hand OpenSSL benchmark. That motivated
me to do some comparing benchmarks. I noted the following numbers of
the 16 size blocks test:

Raspberry Pi B NetBSD   ~70.000
Raspberry Pi B Raspian   ~300.000
Raspberry Pi 2 Raspian   ~800.000
NetBSD amd 64              ~4.400.000 (Intel Core 2 Extreme
(686-class), 2826.34 MHz, id 0x10676)

As I suspected before, I do think that there is an issue with NetBSD
performance on arm. In this case, these differences are hard to
understand because this is a userspace-only benchmark. Possible
reasons that came to my mind were

-the code generated by gcc. (E.g. branches instead of conditional
instructions after cmp or CPSR-updating, 's'-suffixed instructions).

-the timter interrupt being incredibly time-consuming (is there a way
to measure, like RDTSC on x86?)

-other optimizations for example in libc in regard to e.g. memset(),
memcpy() and friends (following these ideas:
