It seems to be running slower than usual for me, but it could be a part of the mysterious network problems I've been having; basically, despite all of the tests I know how to run telling me that my network is fast and reliable, about the only sites that consistently load for me are Google and Facebook. Everything else has a tendency to throw up an error instead of loading. I'm not sure what it's going on, but it's effecting every computer in the house.
A note to the people who are waiting more than a few seconds for a post to upload: your post probably went through in the first 30 seconds or so. Try opening another tab to the thread; your post should be there. This is a bug that I've been encountering since well before the update, although the frequency has gone up since they redesigned the site.
