In the following speed table, smaller numbers are better. The numbers are interquartile means of single-core cycle counts on various microarchitectures. Overclocking is disabled.

Microarchitectures are listed in reverse chronological order of when they were introduced.
In the libmceliece distribution,
command/mceliece-speed.c
measures libmceliece;
benchmarks/*-*
is the output of mceliece-speed
on various machines;
and autogen/md-speed
extracts the table from those measurements.
The table reports only interquartile means of cycle counts. See the full output files for differences between multiple measurements and the interquartile mean.
