EasyDiscuss Optimization Tips

I am looking for tips on how I can better optimize my EasyDiscuss forum. I have been contacted by my server company because recent increased activity on my forum has put a strain on my server's CPU. They claim the majority of the CPU usage is due to the EasyDiscuss add-on to my website. I have added an optimization plug-in to my Joomla website that helps the site's optimization/speed/CPU usage overall, but it doesn't work on the EasyDiscuss section of the site. I am wondering if there is some way to make EasyDiscuss work faster and more efficiently without straining the server's energy? Are there some settings I should be turning on or off? Is there a few tips that you might be able to share with me so that EasyDiscuss will work even better? I'm open to all ideas! Thanks!
