I guess Adobe developers broke the rule: run your software on a machine that’s 100% slower than your customer’s. That way, you’ll be damn sure to make the application as speedy as possible. The Adobe Reader 6.0 isn’t. I browsed the internet and found that you could speed it up considerably by getting rid of the plugins in Program Files/Adobe/Acrobat 6.0/Reader/plug_ins you don’t need. Even after trimming the plugins, this version still has an annoying problem in Mozilla of taking many seconds to “release” itself when you close the tab showing a PDF file.
