I don't think so, look at the Dev-Log ;) http://www.php-fusion.co.uk/readartic...icle_id=28 There are a lot of changes in the background, too. And don't forget this is an alpha version and not a release candidate :P And the performence in v7 is better than in v6 ;)
and the overall performance of php fusion is better than that of many other php cms, gozoc. i have given you some stats from a benchmark riklaunim made some time ago, remember?
I voted "I love it" but at the end of the day all we are seeing is the end user perspective / new theme. As site admins, the bits we are interested in are the bits we can't currently look at - admin panel etc. All the work is under the hood so to speak!;)
