Aside from Google Zopfli there is some more Linux/open-source compression algorithm news today. The LZO compression/decompression support within the Linux kernel has been updated against upstream. LZO in Linux 3.9 will now be much faster.

The Git commit updating the Linux kernel's LZO code against upstream LZO shows off these magnificent performance gains.

Both compression and decompression speeds are now much faster, as measured for i386, x86_64, and ARM Architectures. LZO-2005 was the version used in Linux 3.8 and up to now, which is based upon the LZO 2.02 release from 2005. For Linux 3.9 is now finally kernel code that matches the LZO's latest upstream code. There's also a yet-to-be-merged ARM Unaligned Access patch that can improve the performance even more for ARM hardware.
