TARZ — Texture Adaptive RANS

[kj911]

I ran a quick test using the standard 100MB test archive (a file compressed with the `XZLib+srep:m3f:a0` chain).

If you want to keep things very simple—and don't mind a 10–20% drop in decompression speed—you can use: `d128:l9:cm1`.

Using `cm0` results at the cost of a roughly 1% loss in compression ratio.

LOLZ is 4–5 times faster than TARZ, even when running on a single thread. It is faster with the aforementioned settings; however, I haven't tested it yet on files larger than 1GB, due to considerations regarding thread utilization and memory requirements.

You can see the results of several experiments in the text file below. The patched `cls-filter` also works on XP! It is slow in that environment, though; its benefits are only truly noticeable on a machine with at least 2–4 CPU cores/threads—even if you happen to be running 32-bit XP or Windows 7.
