Phew, had me worried for a minute. I'm writing a simple XML 1.0 parser in #Rust just for practice, and on feeding it a 4.4MB XML file it took 56.5s to read it. I've done nothing to optimise it yet, but even so that sounded dire.
Then I remembered to use "release" mode, and the time dropped to 3.9s. Whatever the compiler is doing behind the scenes, I'll take that 14x speed boost, thank you.
