I agree. Since the upgrade, average times seem to be a bit quicker, but there are still slowdowns that, at least to me, render the site unusable. On multiple occasions, I've waited 2 to 3 minutes for a page to load, and I've also gotten "this connection has timed out" notices several times.
Chat is pretty much impossible. My TUGs friends and I have started using email or Fetlife PMs to communicate.
On a couple of occasions, I had to abort uploading installments to one of my stories because the pages loaded so slowly or timed out.
Being able to read others' stories and communicate with like-minded kinksters is great, but the continued slowness of the board is turning an otherwise pleasurable diversion into an ongoing source of aggravation.
EDIT: Case in point -- it took this post 2 minutes and 1 second to load.
