I was about to write a post about how this update did NOT take care of the slow login problem, when I tried a couple more logins/outs. I has definately made a difference, life is good.

It appears the first time a user logs in and policies come down to create local profiles and push down group policies, it does take a little while for everything to filter down. However, once that has run a time or two, it seems to work quite well.

Thanks for saving our necks, devs.
