Test name	Executions per second
Splice	172.1 Ops/sec
Temp	4299.3 Ops/sec

Script Preparation code:

var tests = 100,
    ct = 100000,
    arr = [];
for (var i = 0; i < ct; i++) {
  arr[i] = Math.floor(Math.random() * ct) + 1;
}

Tests:

Splice
for (var i = tests; i--;) { var from = Math.floor(Math.random() * ct) + 1, to = Math.floor(Math.random() * ct) + 1, fromArr = arr.splice(from, 1); arr.splice(to, 0, fromArr[0]); }
Temp
for (var i = tests; i--;) { var from = Math.floor(Math.random() * ct) + 1, to = Math.floor(Math.random() * ct) + 1, tmp = arr[from]; arr[from] = arr[to]; arr[to] = tmp; }
