>Does the pack compression program slow down the execution of a program?

No...  PACK doesn't affect the execution speed of a program at all..
 
Essentially what PACK does is to create a "self dissolving" ARChive of
a program...  when you load it, it "unPACKs" itself into memory, and
becomes the same as if you'd loaded a normal version of the program..
 
In addition to the savings in disk storage space, LARGE programs may actually
load FASTER when they're packed...  this is because the smaller PACKed
file loads in less time than the original file does,  and the unPACKing takes
place in RAM, which is very fast...
 
Probably the best answer would be for you to try it yourself and see how
it works for you...
