Alas, the comparison presents strangely low GMP scores. When I time it
now, I get 4900 ops/s while the slides say the very exact number 2738.9.
No, I don't get that. I tried to make sense of the numbers in the
slides, and in the end did not measure the right thing.
I don't understand the number 2738.9. It does not make sense for any
common RSA length for the CPU in question. Did the guy multiply a
one-core score by 4? Then we're getting close, I'd get about 3430 for
that CPU (or about 6400 on a current high-end AMD CPU).
