    SquashFS Getting Major Performance Enhancements

    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...

    Anyone knows if or when this will make it into OpenWrt Barrier Breaker? I'm still running April's 12.09 Attitude Adjustment but it looks like I might have a reason to upgrade now :P

        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.

          For the default, zlib, the extra RAM from the multithreaded code is measured in tens of K per thread. If you happen to use XZ, then a lot more.

            Patches, ha? Although I compiled my fair share of kernels, I oddly enough can't recall ever rolling my own OpenWRT... I suppose I just need to clear a weekend or two Thanks!

              The performance enhancements are optional, configured at build time.

              This will work with existing squashfs files.
