Why is Fast User Switching in Vista so slow?

With Linux I can hit ctrl-alt-F7, ctrl-alt-F8, etc to switch X servers (with
different users logged in to each X server), and it's instantaneous. But in
Vista on the same hardware, when I use FUS, it takes at least 15 seconds
even if just two users are logged in and they aren't running any programs,
with Vista reporting that only about half of my 1GB of RAM is in use. Why is
it so slow?

the version in vista is called "slow user switching"

:-)

I'm running RC2. Which release of Vista are you using?
