Here we see the source code written in the C# that issues commands to the browsers specified in the static string array. All the five browsers support command-line arguments of the form of a URL with no prefix. The program uses pauses with the Thread.Sleep method to try to introduce more unpredictability into the benchmark. This could avoid edge cases where the a certain timing could interact with a browser's cache algorithms in a less representative way.Firefox 3.5 also had the best average memory usage figures, meaning that it may consume the least memory of these browsers when used for the Alexa sites as tested in the benchmark. Finally, Chrome and Firefox posted the best memory figures at the end of the browsing session, with Opera consuming 4.1 times more memory than Firefox at the end of the test.
