GWT Java benchmarks, Java SE7 vs GWT+JavascriptVM (no multimedia) (opens in new tab)

GWT (Google Web Toolkit) is a tool for compiling Java into JavaScript code; with GWT you can write both your web application and your server side code using the Java language.

What about Google Web Toolkit performance?

I have worked with GWT in the recent years and a simple question has arisen: "What is the performance of the same Java code when running inside the Java virtual machine VS running inside the browser?"

I have decided to do a bunch experiments and write this article after taking in account these facts: 1)GWT developers state that the generated JavaScript code may be better than the handwritten one. 2)V8 JavaScript Engine and the other JavaScript engines have been highly improved in the recent years

It also makes sense to measure the perormance of GWT applications running on different browsers, Firefox, Opera, Chrome, Explorer in order to see who sucks and who rules.

I think that these results may be useful from a distribuited High Perfomance Computing perspective (via web client).

These benchmark covers numeric and data crunching and string manipulation; Multimedia and rendering are not benchmarked.

Have fun! Fabiano
