Startup under the main profile seems a little faster. The system still goes to a crawl when playing a downloaded video file. The usual websites (yahoo, cnn.com, google) seem to come up a little faster. Other websites that are a little graphics focused come up a little quicker, as well.
IE, Avant, and Firefox seem a little more responsive now, not as sluggish as before.
Edit: An exception is when IE tries to bring up something just a little large, textwise... like this thread.
At that point, it "waits for the site", but it doesn't bring anything up for quite a while.
