Timing like hattmoward did, I get 13 seconds for both, so I see no time-to-load issue for me.

I am very impressed by the looks of it (++demerphq's work).
I am also very happy with the new usability too. Yay!

What I like to preserve though is that PM isn't working too much the same way Usenet News does - at least in my perception. All questions on top, waiting for people to find answers to them.
Presented in this way ,PM's newest nodes look more like Usenet, threaded and such... well, we will see it evolve.
