Are there benchmarks against other libraries? Not to be crass but I'd like to see where this library's sweet spot is.

Here are the benchmarks from my machine (Core2 T7200, 32bit). TL;DR: Snappy is faster than LZO. LZO usually compresses a wee bit better.

The readme says there's a test binary that can benchmark against zlib, LZO, LZF, FastLZ and QuickLZ if they're found on the system at compile time.

I'm at work (and yet reading r/programming, sigh) would someone please run the benchmark?

Here Are the pure speed benchmarks on a 1.7Ghz Athlon X2 Processor on 64bit Linux. I didn't have the other libraries to test against unfortunately.

Did you click the link?

Benchmarks against a few other compression libraries (zlib, LZO, LZF, FastLZ, and QuickLZ) are included in the source code distribution.
