I must say I believe it.  On one of our systems:

uts ihlpj 5.2.5 5 5890

(ie an amdahl 5890 running Unix 5.2.5)

I can build GNU emacs from scratch in less than a minute.  I would
then guess that that is real time.  Also (as a guess) I would say
optimized as I would suppose they are running (as I was) the native
mode compiler.  Check out the Dhrystones for these beasties.  Quite
impressive and they do live up to it.
