Till I add some documentation here, go to the forum thread for info.

Download and info at: http://hulan.info/blog/item/np-cache-static-pages-for-nucleus-cms-v0-2
NP_Cache is a new plugin for Nucleus CMS, compatible with version Nucleus 2.0 and above, including its standard, eXtreme Edition, and Light Edition distributions. It creates static pages real-time, automatically, refreshes them as needed. It also calculates some statistics as well. It is based on Cache_Lite PHP class.
Without this plugin, it takes about 0.2 seconds to create a homepage of my blog. With this plugin installed, it takes only 0.0007 seconds! Quite a difference..
