I like the occasional batch of change, and I think this was a good one. I am not freaked out, I just want to mention that the upgrade made so difference at all in the site's performance for me. I am still reloading pages 3-8 times to get them to open or post today.
I did a thorough cleaning and clearing and resetting modem, because I did not want this to be true.
It is a tad faster, but, indeed, still requires reloading. It isn't as fast as it was a month ago.
