It's not compiled in the way that C is compiled. Transpiled would be a better term (though there are debates on where the line is). Amber code gets turned into bash code, and run by a bash interpreter. So at best Amber's performance will match Bash's performance. I've seen people say bash is faster than PowerShell, but I don't have benchmarks to back it up. Even so, I wouldn't recommend using it for performance intensive tasks such as writing a web server. The great advantage I see for Amber is being able to write scripts in a sane language (bash is not enjoyable to write), and have those scripts be able to run anywhere that Bash is installed.
