Here are more objective numbers. I timed 1000 runs of wg genkey | wg
pubkey > /dev/null. Each timing was done four times for both MIPS16
and MIPS32 and the worst results were chosen.

MIPS32 results:
real    0m 10.06s
user    0m 8.12s
sys    0m 1.34s

MIPS16 results:
real    0m 11.96s
user    0m 10.14s
sys    0m 1.15s

I'd say the difference is, indeed, negligible.

Thanks,
Rui
