FWIW, I'd find your emacs22 time pretty unacceptable, never mind the 
emacs23 one, even on a 1.2GHz-class machine. Are a lot of people
putting up with that sort of start time? Ouch.

Of course it could be an emacs bug triggered on your system and not 
mine, but I kinda wonder: is it only emacs or is everything slow? Is it 
only slow to start or slow to update the display and whatnot?  Makes me 
think you might have a local system issue causing an I/O bottleneck, is 
all, maybe no DMA on your HDD, or your system's low on RAM and is 
already swapping or something.

On my admittedly higher-end newish multicore (but each core is only ~ 
2GHz and emacs isn't parallelized...) gnu+linux system, emacs23 takes 1 
to 2 seconds to start, including the ridiculous happy-dance across the 
screen the initial X11 frame does (known-bug afaik), and I thought it 
was getting a bit sluggish (whenever an app start time is > 1 sec I 
start to notice and get irritated), but I put it down to the 
happy-dancing.   With a .emacs.desktop of 100 random .el files from the 
emacs source tree, start time was 2 to 3 seconds.

Iceweasel takes 2 to 3 secs and oowriter (probably the bloatiest thing I 
have installed)  11 secs ?
