In a three-way cage match, LifeHacker threw Chrome 4, Firefox 3.5, and Opera 10 into the ring and let the three browsers duke it out to see which would emerge as the fastest app for surfing the web.

A number of tests were run, including a “cold start” right after boot, a “warm start” after the browsers have already run once measuring the time it takes 8 tabs to load, a JavaScript testing suite, and memory utilization.

Opera turned in the best cold start time and was slightly slower than Firefox 3.5 with a warm start, while Chrome trailed the competition in both. But once the browsers were open and it came time to load 8 tabs, Chrome whipped both Opera and Firefox by loading up to about 1.5 seconds faster. Chrome also performed best in JavaScript testing, but was far less efficient in memory utilization with 8 tabs open than either of the two other browsers.
