On the other hand, the new completion system does more in its shipping

Sven did a couple of optimizations posted in zsh-workers/13589 that
should both increase the speed and cut down the memory usage a lot.  If
you haven't tried again with the latest snapshot, you should.  Or at
least try again when 4.0.1 is released.

Maybe; the .zcompdump file actually does make a lot of difference.  In
tests I just tried (on a 233MHz Pentium II), "zsh -li" started in 1.05
seconds with a .zcompdump file, as opposed to 2.35s with "compinit -D"
(other garbage in my startup files being equal).  Incidentally, it took
3.64s to start up and write the .zcompdump in the first place.

compinit -C cut the time from 1.05s to 1.01s.
