How I wish to believe this! But only when OZ comes on here personally and tells us that he has spent an hour creating a post only to have it disappear into thin air will I believe his suffering has been commensurate with ours.
Thankfully, I have noticed the site getting quicker than it was last week.
I also realize that when I've said the site was 'slow', I may have been misstating what's actually been going on for me. In truth, when a page actually starts to load, it seems pretty speedy. What's been different since the 'upgrade' is that some pages (down from most pages last week) just hang with the progress bar stuck at about 10%. Then, all at once, something will come unstuck and the page finishes loading.
I started trying to find out what would cause this type of behavior, especially since switching from Safari to Firefox seems to make the issue go away, at least for me. I cleaned out the Safari cache, and that didn't help. So today I changed my default Domain Name Server to see if that solves the problem. So far, so good.
Anyway, a little progress report, and a fervent hope that this post will see the light of day.
