That > is, would bzip2 be an issue on older, low-spec machines? I understand that the downside in using bzip2 is not speed but memory consumption. But I'm not an expert in this. I only know that the "b" in bzip is for "block oriented" and that's why you see the decompressor "jump in chunks" and you definitely need a larger buffer than for gzipped archives. Adding the special needs of an install floppy (ramdisk) it could raise memory requirements a little more. Unless you restrict yourself to "moderate" parameters at compression time. That's probably where the "we don't gain 40KB but some 15KB" stated in another article comes from. As stated above that's my simple understanding from using these programs and not from fiddling with their internals. virtually yours 82D1 9B9C 01DC 4FB4 D7B4 61BE 3F49 4F77 72DE DA76 Gerhard Sittig true | mail -s "get gpg key" Gerhard.Sittig@gmx.net -- If you don't understand or are scared by any of the above ask your parents or an adult to help you.
