Adobe Reader is a one of the most used PDF reader.But the main thing in it which makes people to dislike it is that it takes lots of time to start.
Actually it loads all plugins at startup.PDF SpeedUp allows you to significantly speed up the time it takes to load Adobe Reader. If you notice that when the Reader starts it loads many plug-ins which you may or may not need, this program simply disables the plug-ins and loads only the absolute necessary ones so the program starts quickly. It offers several options and you can also manually enable or disable the plug-ins as needed. PDF SpeedUp works with Acrobat versions 5 through 9.
