# speci.js - specialization benchmark test

Tests two-property objects with {x, y} or {y, x} and access in a tight loop
When the array contains consistent elements it optimizes well, but the first
run is much slower on a randomly mixed array.

Subsequent runs come up much faster as the higher-tier compilers in V8 can
handle a couple of different variants -- but this might not be true of all
possibilities. 256 randomized variants is linearly slower.
