That site is very slick!
I did click on several threads and posts, just to see how the pages loaded. They load very fast on that site.....HOWEVER......that site does not contain all the links, images, and videos we have here. This definitely makes a difference. I also noticed they don't have all the advertisements we have here. I am assuming that site has Google Adsense.......CRF uses something different. The advertising service can be a huge hog of ram.
Just an FYI, CRF does it's forum maintenance cycle in the middle of the night, and this can make pages load like a turtle.......sometimes it can even "time out" your browser.
