Hi Monika, the performance differences between browsers can be pretty vast, depending on which versions you're comparing. Older versions of IE are notoriously slow in both JavaScript execution and HTML rendering, while the newest WebKit-based browsers such as Chrome 3 and Safari 4 are blazingly fast.
For example, during our nightly test runs, IE7 takes around 20 minutes to run all the framework unit tests, while IE8 and FF3.5 only take around 12 minutes. Safari 4 and Chrome 3 take just over 6 minutes. But you have to keep in mind that unit tests are very much unlike a real-world application, where often the biggest issue from a user's perspective is how responsive the UI feels. One optimization that can make a big difference especially in IE is to keep the number of widgets created during runtime low. This as well as some other best practices for application development is discussed here: http://qooxdoo.org/documentation/0.8/enterprise_application_development Regards, Daniel [email protected] schrieb: > > Hi Burak > > I have seen this JavaScript framework comparisons, but this is not really > what I meant.
