It seems to be about the same, that's to say its been loading pretty fast the last couple of months anyway, the only page that isn't is my postings which is taking an age, but I suppose that something to do with loading the database.
I switched to using Opera for PCA recently, having had very slow loading times in Firefox. The speed increase, particularly for My Postings, was huge. However, it has slowed down today, though that might be coincidental.
It was very slow to make a post for me earlier and My Postings seems very slow. Search this at about 5:00pm was very slow, but has now picked up. The appearance is good though! I will see how long it takes to post this message and come back.
