LZHAM v1.0 is back on the Pareto frontier for decompression speed

LZHAM v1.0 is doing pretty good on this benchmark:

lzham 1.0 -d29 -x 25,002,070  202,237,199  191,600 s  202,428,799  1096  6.6 7800 LZ77 70

Thanks to Michael Crogan for giving me the heads up.

About Me

Rich Geldreich: Seattle, WA, United States; Back in the day I worked for several years at Digital Illusions on things like the first shipping deferred shaded game ("Shrek" - 2001), software renderers, and game AI. Then, after working for Microsoft at Ensemble Studios for 5 years as engine lead on Halo Wars, I took a year off to create "crunch", an advanced DXTc texture compression library. I then worked 5 years at Valve, where I contributed to Portal 2, Dota 2, CS:GO, and the Linux versions of Valve's Source1 games. I was one of the original developers on the Steam Linux team, where I worked with a (somewhat enigmatic) multi-billionare on proving that OpenGL could still hold its own vs. Direct3D. I also started the vogl (Valve's OpenGL debugger) project from scratch, which I worked on for over a year. In my spare time I work on various open source lossless and texture compression projects: crunch, LZHAM, miniz, jpeg-compressor, and picojpeg.
