Comment Use xz compression (lzma) (Score 4, Informative) 488
Why won't ubuntu just do as fedora has done? use xz compression on the squashfs image. The live image for fedora is now 565 MB, but would have been more than 700MB if using gzip compression as ubuntu does.
Reading from cd/dvd or even flash drives and harddrives (except ssds) are so slow compared to the cpu today anyway, so it would probably be faster in most cases.
