- Pretty much double. It really depends on what you are storing on your hard
- disk. Running stacker is like keeping _everything_ on your hard disk
- compressed, aka pkzip.
-
- i.e. If you have tons of gifs, digitized sounds, and programs compressed
- with pklite, then expect _zero_ compression.
-
- if you have normal everyday files, etc, expect roughly double. (nice for
- windows, since windows can't have pklite run on them)
-
- If you got lotsa small files, then expect a surprising amount of 'compression'
- due to merging these files and wasting less space.

-
- Well, for the most part, no. According to my experimentation, Stacker has
- some overhead when you 1st load the file, and after that, nothing. So, if
- you run a big file, no problem.
-
- If you are opening and closing _lots_ of small files really fast, it slows
- to a rock. I discovered this when I was testing a stock analysis program I
- had written - one of the algorithms computes a worksheet for each of the 200
- individual companies, and saves a line of data from each one into a file.
- then it loads the final file for analysis. When doing this particular
- analysis, the program sloooooowed way down. besides that, it ran fine.
