In March I ran the Acid 3 web browser stress test against all the most modern browsers at the time to see how they performed. Since then, there are new versions of browsers which justify a re-run of the tests. Here are the results:

• Mozilla Firefox 3.0.1 – 71/100
• Google Chrome 0.2.149.29 – 79.100
• Opera 9.52 – 83/100
• Windows Internet Explorer 7.0.5730.13 – Too bad to tell. Perhaps 5/100?
• Apple’s Safari 3.1.2 (525.21) – 75/100
• Flock 1.2.5 – 53/100

All the web browsers were run on the same Windows XP system.

Then, out of curiosity, I decided to check the memory usage of each browser and found the following:

• Mozilla Firefox 3.0.1 – 55M (After all add-ons were turned off)
• Google Chrome 0.2.149.29 – 41M
• Opera 9.52 – 27M (But then crashed on subsequent loads)
• Windows Internet Explorer 7.0.5730.13 – 41M (But still couldn’t render the test at all)
• Apple’s Safari 3.1.2 (525.21) – 41M
• Flock 1.2.5 – 54M
