Smallest timeout value (v27)

Revision 27 of this benchmark created on

Description

The smallest setTimeout timeout value allowed by the HTML5 specification is 4 ms. Smaller values should clamp to 4 ms.

Therefore, the first two tests below should have about the same result.

P.S. Some browsers freak out when you use a value greater than 599147937791 for the timeout (i.e. they use 0 or 4 ms instead), hence the last test.

Preparation HTML

<script>
function Callback()
{
   d.resolve();
}
</script>
