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.
