Leave out html, head, body and title.
|
| + <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> |
| + <title>Adding whitespace performance test</title> |
| + <script src="../resources/runner.js"></script> |

| + var target = document.getElementById("test"); |
| + function test() { |
| + target.innerHTML = '<div style="display: inline-block;"></div>'; |

Why inline block?
|
| + for (var i = 0; i < 1000; i++) { |
| + var testElement = document.createTextNode(" "); |

This is not very realistic, pages don't have huge
|
| + target.insertBefore(testElement, target.firstChild); |
| + } |
| + document.body.offsetTop; |
| + } |
| + |
| + PerfTestRunner.measureRunsPerSecond({ |

| + run: test |
| + }); |
