Starting from Jom Comment 1.8, we will be using a completely new template system. It is a super-fast, super efficient PHP-based template system. It doesn't do the typical 'search and replace' which most template does.

On top of that, we also have a new caching system in place.  We no longer have to rebuild the comment area at every page load. Of course, if you are already using Joomla built-in caching system, your content (along with Jom Comment)  are already cached in anyway.

I run some benchmark and building Jom Comment page now takes between 0.002 to 0. 005 seconds compared to non-cached time of 0.10 to o.15 seconds! That's 75x performance increase.

Anyway, as I said before, if your site already have Joomla caching turned on, this doesn't really mean much to you.
