How many seconds does it take to run "sed -n -e s/xyzzy/xyzzy/p" on
all those files, on that machine? (That should give us a baseline of
the disk and filesystem performance.)

Can you see if some files your desktop visits take much longer than
others?
How about loading elp.el early on and profiling the startup phase on
both versions?
On GNU/Linux, FreeBSD, and MS-Windows, you can also profile Emacs on
the C level, search for PROFILING in emacs.c.
