    <p>JS Object Storage Performance</p>

    <h1>Test Description</h1>
    <p>Create 10.000 new (non stored) objects inside a loop. Identical to LocalObject_1.html.</p>

    <h1>Result</h1>
    <p>The performance in IE is quite good (~330ms for each loop), compared to the same stuff executed without the precreated stuff.</p>
