The statement, that there is no benchmark to measure well F21's
performance (and MISC's for that matter) has surfaces several times here.
I would again draw the attention of the readership to the HINT benchmark.
Note, that its author /John Gustafson/ has not yet heard of the existence
of the MISC design, so the benchmark is not designed to show how great
MISC is.
