I installed ColdFusion 8 on this server today, and so far have had no problems. Pages definitely feel zippier to me when I browse them. I haven't done any timing tests yet, but I'll take Adobe's word for it that things are much faster in CF 8. Flash Remoting apps seem to be working as well, which is always something I worry about when upgrading. As I'm going on vacation for 8 days, I'm crossing my fingers that everything keeps running smoothly.
