I did some quick and dirty compression testing today on an H120 build zip (size is in kbyte, rounded to the nearest 4k):
(original) rockbox.zip 2046 (gzip -9) rockbox.tar.gz 1794 (12%) (bzip2) rockbox.tar.bz2 1802 (12%) (p7zip) rockbox.tar.7z 1297 (37%) (rzip -9) rockboz.tar.rz 1738 (15%) Interesting that the bzip2 tarball actually came out slightly bigger than the gzip tarball. This shows that with small files compression statistics can get a little strange. Clearly 7zip is the winner, but even then it's only saving 750k per build. Here's a table showing the uncompressed space used by each top-level directory in an H120 build (this is /usr/bin/du output so there's some rounding): 0 ./eqs 1.3M ./wps 20K ./docs 3.9M ./fonts 253K ./langs 882K ./rocks 588K ./codecs 36K ./themes 232K ./viewers 0 ./backdrops 260K ./codepages 7.4M . Out of a total of 7.4MB, the binary and lang components take up 2.22MB. The themes/WPS/fonts take up 5.24MB (~70% of the total). Separating the two would be a big space/bandwidth win. bk
