Yes, a very advanced JIT is faster than an interpreter.

Python 3 is slow, one should compare PyPy, HHVM-PHP, LuaJIT, etc. A company did that back in Dezember: http://www.techempower.com/benchmarks/#section=data-r8&hw=i7&test=update http://www.techempower.com/benchmarks/#section=data-r8&hw=i7... (found it on HN) Revel uses LuaJIT (afaik), HHVM is HipHop PHP (Facebook) and you can find PyPy there too.

  That benchmark isn't benchmarking what you think it is. "This test exercises database writes. Each request is processed by fetching multiple rows from a simple database table, converting the rows to in-memory objects, modifying one attribute of each object in memory, updating each associated row in the database individually, and then serializing the list of objects as a JSON response." You're actually just benchmarking the mysql driver for each of those languages, not the actual JIT capabilities.

    The website design is a bit confusing, you probably missed the other tabs: "JSON serialization", "Single query", "Multiple queries", "Fortunes", "Data updates", "Plaintext". It's a micro benchmark but at least it covers a lot of languages and frameworks. (I saw that benchmark site on HN some months ago)
