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.
