It works quite nice! Very useful info, thank you.
There are some things you can do in Reader itself to speed up loading, namely:
Get rid of the splash screen (Edit > Preferences > Startup > Display splash screen
Change settings in Edit > Preferences > Internet:
uncheck 'Display PDF in browser' and 'Check browser settings'. check 'allow fast web view'.
These work for me and have visibly, if not dramatically increased PDF loading times.
