On our test XF site, where we're setting things up to convert our main board (currently on vB), only our staff members have access (there are 8 of us). We have two custom themes set up and 2540 posts. Some of our staff members are convinced that the XF board is much slower to load than the vB board (2,928 members and 1,122,568 posts). I don't see it being slower personally, but that might be because my internet connection is pretty crap and so it's hard to tell. I've done most of what was suggested in the Quickly and Greatly speed up your XenForo thread, and that seemed to have helped on my end, though it's hard to tell just how much of a difference it's made. The staff members who were complaining that it's slower to load say it's still slower than our vB forum. I don't know how to tell if it really is slower or not, and I don't know what else to try. Any suggestions would be much appreciated!
