Phoronix: SquashFS Getting Major Performance Enhancements
SquashFS is commonly used by Linux distributions as a compressed read-only file-system commonly used by the Live CD/DVD/USB versions of distributions like Ubuntu, Arch, Fedora, Debian, etc. There's some performance improvements to be merged into the Linux kernel that will make SquashFS even faster. SquashFS decompression can be multiple times faster with these patches...
Patches for Linux Kernel 3.12
Holy crap that's a huge performance boost, but at what cost? The extra RAM used might be a problem for lower-end systems.
I'm assuming this works with currently existing squashfs files? I've got 8.5GB compressed into a ~4GB file and I'd be happy if it were to load faster.
