Firefox 3 Memory Benchmarks and Comparison - Safari Appears the Worst

Posted by sudhirmangla July 4, 2008

Web browser performance is an often talked-about and flaunted thing, but many claims are not really backed up by solid evidence. I wrote software that collected millions of data points over 14 hours of actual browsing time, and this article reveals my findings.
Problem
Many people load hundreds of web pages, sometimes at the same time, often over periods of 3+ hours. Users complain about the memory usage of Firefox, Safari, or Internet Explorer, and we need a way to identify which browsers are better at managing memory than others. Traditional benchmarks do not look at all the things you might do with a program, and we need real-world numbers over a period of hours.
Solution
I developed a Windows Forms application in .NET called Memory Watcher that "watches" the system memory numbers. It uses a timer to poll the processes every 3 seconds. It then records every number and also prints them out in a grid on the screen. This allows us to keep track of each program’s memory usage over time and with real-world usage.

Good to see FX3 improving on FX2!
