21.3 is three to four times faster than 21.2 when loading files at
startup.
I just made objective measurements and confirmed a subjective
impression that 21.3 smokes 21.2 at startup. In summary, it is three
times faster at loading the same disk files, and subtract 5 more
seconds for not having to load Mule-ucs (this bumps to ratio to four
times faster for me).
These results not controlled enough to be a reliable benchmark. The
compilation of 21.2 may have been done with gcc-2.95 vs gcc-3.2, and
of the approx 100 files loaded, a handful are not the same in each
case. But whatever the cause, it sure is a delight.
(The output below is generated by code I wrote to measure and
summarize the time it takes to `require' files at startup (I will put
it on gnu.emacs.sources when it is more polished.)

It takes about 5 seconds to load Mule-ucs
in Emacs 21.2, so the figures for file-loading are
about 3:1 and for starting up overall, 4:1.
