    QuickLZ 1.50 prototype (win64 only)

    I'm currently tuning level 2 for 64-bit machines for use in a future QuickLZ 1.50: http://www.quicklz.com/quick150_64.exe (for XP64 and Vista64 only)

    The only difference from 1.40 level 2 is the match finder which is very neat Will release sources later. I just couldn't wait announcing these speeds:

    Library; Level; Compressed size; Compression speed:

    I love how people are "attacking" LZO in the speed wars. It's the watermark to beat: If you can beat LZO at compression speed, you "win"

    What I really want to see are DEcompression times. Hardly anyone reports those in these quick'n'dirty benchmarks...
