The Disk Activity pane can show disk I/O bandwidth, so maybe getting a
faster hard drive would help, to make the swapping faster.
You said it was thrashing just when going back and forth between Xcode and
Safari. Given all that's running, I can understand a flurry of page-outs
once or twice, but then the active sets should encompass Xcode and Safari,
with everything else mostly quiescent. Little or no additional swapping
should occur until one of the other apps does something demands a major
swap-in.
If you're really using all those apps equally at the same time, the only
other suggestion I have is to upgrade to a machine that can accept more
RAM, or to use software that consumes less RAM. I know of no other way to
reduce memory consumption than to consume less memory. Maybe don't compose
emails in Safari.
