Nice. It's a bit weird, but it makes sense. Stdout is already line buffered, but a bigger / equal buffer will make writes pass through, so it's not really double buffering fortunately. This is issue #10279. Looks like regex 1.30 is broken by lint changes in the benchmarks game by the way. Probably just needs a version bump. |

@bluss Yeah. If I recall correctly, using a newer version also requires using the regex_syntax crate (I'm not sure when the split happened, though). I've set up an issue at teXitoi's repo. |

Since 1.3.0 the BufWriter has seen tremendous speedups. So when I use it in the shootout benchmarks, I see some nice speedup (which up to 1.2.0 was nixed by the pessimizations during initialization).
