UPX always good?
I just found out about UPX on this site and it seems like a very clever thing to use on portable programs. What I now wonder is three things.
1. Is it always good? Or can it cause unwanted problems in the programs?
2. What is the "downside" of it? Does it take more memory? Does it make the programs run slower from for example USB sticks?(USB 1.1? USB 2.0?)
3. What parameters should be used?
