Hey, don't be so hard on my poor little PC! It's getting on a bit[*].
There's 83 files being loaded by desktop, with a total of 7801019 bytes.
emacs-22 -Q starts in ~0.4 seconds.
emacs-23 -Q starts in ~0.7 seconds.
[*] For non-native English speakers: "he's getting on a bit" is a
euphemism for "he's too old (for something)".

It's a 7 year old PC, with a 7 yo HDD, but with plenty of RAM (768 Mb).
You really think 23 seconds is slow, loading emacs + 83 files?

How many file does your desktop load, and what's their total size?

OK, 100 random files.el. How big were they?

Firefox 1.0.4 takes ~2.5 secs to load (but it was probably in the disk
cache when I timed it).
