Tomasz Chmielewski presented the following explanation : > http://digitizor.com/2010/11/17/internet-explorer-9-caught-cheating-in-sunspider-benchmark/ > > 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. Kolejny który nie słyszał o dead code elimination. -- Piotr Borkowski
