Copied from drplokta - if you've ever wondered why Adobe Acrobat is so slow, it's because it's installing loads of plug-ins that it probably doesn't need whenever you run it. Running Acrobat Reader Speedup fixes that. I tried a couple of big documents that were painfully slow last time I looked, they're now loading about four times as fast. It's a 78k download, a zip file containing a program that you run once; you can tweak settings if necessary but it shouldn't be. But keep the program, if you want to upgrade Acrobat you'll probably need to return to the full set of plug-ins.
