It is a balance between amount of software in the CD and decompression performance. LZMA decompression is a heavy-hitter on the CPU and is only suitable for well-endowed machines otherwise there are performance issues and install can take ages maxing out CPUs for the entire duration. So this option of gzip is provided. > Primary Languages CD, gzip compression, 687M > All Languages CD, LZMA compression, 639M > > Primary Languages USB, gzip compression, 824M > All Languages USB, LZMA compression, 767M > Uncompressed size of the LZMA image will be much larger than uncompressed size of the Gzip image in both cases.
