Looking for info on "cache" feature
TikiWiki 1.8.3. - I'm currently trying to boost our rather slow performance without bugging our provider (I want to make sure I've optimized anything possible on my side first) and stumbled over a feature named "cache" on the wiki admin page. I blindly switched it on and things seem to speed up considerably... however, I'd be very interested in understanding how this feature works and found no info in the docs or the forum. There's one setting named "global cache: x minutes" and another one named: individual cache on/off". And when editing a page there's another cache setting for that one. Can someone explain to me what these settings do or point me to a doc?
Thanks,
Hagix
