    Ross Williams high-speed LZRW compressors

    Here's my own speed optimised compile of Ross Williams LZRW series of public domain (open source) compressors . A Pentium Pro or later processor is required.

    See Matt's LTCB page for more information.

    ENJOY!

    You might want to write an LZJB version and see how that compares as well; it's LZRW1a but optimized in various ways (shorter lookbehind, smaller hashes, etc.) so as to be as "realtime" as possible. It's the default "realtime" compression in ZFS.

    Thumbs up

    Thanks for the feedback!

    LZRW3-fast is so fast that it compresses the enwiks almost as quickly as THOR's e1 mode on my Sempron 2400+ machine.

    Here's a couple more experimental builds that give improved compression ratio.

    ENJOY!
