I just compresses using bzip2, and it only saved 8% versus over 50% saved by using NOSSO(r). Here is the bzip2 output 1.080:1, 7.406 bits/byte, 7.42% saved, 2718433280 in, 2516591511 out. The command line I used to compress was bzip2 -9zvv sol-10-u4-ga-x86-dvd.iso Russ Alain Spineux wrote: > Did you try to bzip2 the DVD using -9 options to have something to compare ? > > > On Dec 4, 2007 6:35 PM, Ruslan Sivak <rsivak at istandfor.com> wrote: > >> I just downloaded solaris.
