While Mozilla engineer Rob Sayre was benchmarking Firefox 4 with different browsers, he noticed something with Internet Explorer 9 – Internet Explorer 9 was around 10 times faster than the other browsers in a particular test (math-cordic) in the SunSpider benchmark. While Chrome and Opera scored took around 10ms in that test, Internet Explorer 9 finished it it in about 1ms.

Sayre investigated further by modifying the code for that test used in the SunSpider Benchmark a bit. He made two variations of the test little bits of codes to the original – one by adding a “true” and another by adding a “return”. As these “true” and “return” in this context does not do anything there should be minimal impact.

The result though is startling – Internet Explorer 9 took around 20 times longer with the two new tests compared with the original. While the original took only 1ms in my laptop, the other two took around 20ms each.
