This was just too painful for me (and the suggestions to cleanup the TEMP folder and IE cache didn’t help me), so I switched back to 3.0 for now. Apparently I’m not alone in experiencing this, so hopefully they’ll get it sorted out soon. I always appreciated Internet Explorer’s blazing startup time (about 1 second for a cold start and almost instantaneous for warm). Maybe they will finally make it a priority to improve on startup times in v4.
Update: I was able to get v3.5 cold startup time down to 9 seconds by following the instructions in this article. IE’s cache cleanup must not be very comprehensive, since there was still over 67MB of files there.Permalink
