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.

ENJOY! :)

Thanks LP!

The speed optimized compiles of everything... ;)

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.

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. :cool:

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

ENJOY! :)
