This is simply awesome. I downloaded this neat package called Adobe Reader SpeedUp and it has resulted in my Adobe Acrobat's load time to a trifle few seconds.
It curtails those truckloads of plugins that Acrobat loads with it everytime, ones which I rarely or never require for the innocuous task of reading the pdfs. (One could always do it by pressing Shift while Acrobat loads but this is definitely a convenience.)
So, if you're one who can't do without Adobe Reader/Acrobat in this world, it's time you download this little program.
