For what it's worth...
Slow for me as well, plus I had my first ever case of Google Chrome tabs "locking up".  Had multiple DNN forum pages open at once.  Forums were slow but working. After a couple of hours of intermittant browsing (basically just an occasional page refresh to check for new posts) I suddenly could not scroll, highlight text, etc, and also could not close DNN forum page tabs.  These were all fully-loaded pages (i.e., I was not experiencing a lockup during page load).
 
Other tabs in the same Chrome browser instance continued to work perfectly and I could open/close new tabs without issue.  Eventually had to kill the entire Chrome thread to get the DNN tabs to close.  Re-opened same tabs to same DNN pages upon browser load without any issue.
 
I can't say the issue had a direct connection to the new DNN version and/or forums module but I also had other browsers open to other sites that were unaffected -- only the Chrome tabs open to DNN forums displayed any problem.
