Phoronix: Google Launches "Brotli" Compression Algorithm For The Web

Google has announced today Brotli, "a new compression algorithm for the Internet" that easily defeats other compression algorithms...

You too you see: https://bugzilla.mozilla.org/show_bug.cgi?id=366559 ?
Yes, but zopfli is zlib/gzip compatible (useful for png and all static content or with cache)

Very useful on network stream

I'd love to see some comparisons between Brotli, LZMA2, and XZ (which is a sub-format of LZMA/2 iirc)

Whoops, fixed. Thanks.

while compressing more densely than LZMA -> no, internal benchmark show it, less ratio than lzma (worse for static content or with cache), but better than bzip2 and zlib, with similar compression/decompression speed of zlib or better (depend greatly of the content)

The linked blog post actually says that it compresses more densely in one specific test. They didn't make it a general statement.

Hasn't this been used for the WOFF2 format for months now? So how is it new, exactly?

It's not really new, it's just gotten a *lot* better lately. Until pretty recently it really wasn't competitive.

Brotli has been around for a fairly long time, just recently they've added some optimizations and then then the heuristics for trading compression performance for runtime performance.

Old brotli had great compression but was very very slow. This looks like a potential gzip replacement.
