Still, it's quite remarkable that scripting languages have come from 2
to 3 orders of magnitude slower than native code to only 1 to 2 orders
of magnitude slower, and closer to 1 order with LuaJIT.

Also, automatic memory doesn't have to be wasteful, as Lisp SBCL and
LuaJIT show. According to the Comupter Language Benchmark, they both
consume at least 10 times less memory than Java (more like 20 times for
Lua).
