Benchmark: multiple shift vs splice

Script Preparation code:

var arr = [];
for (i = 0; i < 1000; i++) {
    arr.push(i);
}
var arr2 = [];
arr2.push(arr.slice(0, 199))
arr2.push(arr.slice(200, 399))
arr2.push(arr.slice(400, 599))
arr2.push(arr.slice(600, 799))
arr2.push(arr.slice(800, 999))

Tests:

splice
arr.splice(0,200);
shift
arr2.shift();
