as fast_test()
tool.js is my wrapper around benchmark npm module, feel free to use
whatever you use to benchmark V8 as the problem doesn't seem to be specific

The way Array.prototype.map is specified (see section 15.4.4.19 in the ECMA
spec) makes it very hard to implement
I'd say it's a known issue that generic Array built-ins are slower than
handwritten less generic versions.
Array you are mapping over is extremely small so all overheads of a generic
implementation are highlighted. For example %MoveArrayContents amounts to
20% of the overheads, while in reallity
