FutureMark Peacekeeper v2.0
Chrome lands on top in FutureMark's Peacekeeper benchmark with almost one thousand points. Opera comes in second with nearly 750 points. Safari and Firefox are in a practical tie for third place, both with about 560 points. IE8 only manages a two-digit score of 57, putting it in last place.
Mozilla Kraken v1.1
Google SunSpider v0.9.1
Chrome barely edges out Firefox to place first in Google's modified SunSpider benchmark. Safari places a distant third, followed closely by Opera in fourth. Once again, IE8 did not run this test.
