Good information to Make Acrobat Reader 6 load faster from Darrell Norton's blog (seems everyone links to his blog).
Plus use the Adobe Reader SpeedUp tool to help in selecting plugins (using a graphical checkbox system). I'm going to try just the Search/EScript/Weblink path and see how it goes. Currently Reader v6.0.2 uses 33.5Mb of mem opening with no documents :'(
UPDATE:I went with the SpeedUp tools "Fast" recommendation, only EWH32 (81k) / reflow (305k) / Search (201k). And the cool thing is all other plugins are moved to "optional/" so they will load if the plugin is actually needed...
It seems to load VERY FAST, and now only using 18.5Mb of memory :)
