Performance improvement with Firefox 3.5
We had an application in production running on I. You must be wondering who the hell is still on IE6.
But we have a very heavy UI with touch screen keyboard functionality and our UI consists of Yahoo’s YUI 2.7 and JSP and JSTL. Initially we never supported Firefox and then we did not had bandwidth to fix the whole application.
The new version of application when launched had a very bad performance in field with page load times > 15 sec.
Within our facility , even on QA server we had load time of < 7 seconds on IE. The same application loaded in <4 sec on firefox.
In Firefox 3.5, Mozilla introduced a new high-performance JavaScript engine called TraceMonkey that uses just-in-time compilation and an optimization technique called tracing to deliver faster JavaScript execution.
A decision was taken to upgrade the application to support Firefox 3.5 and we updated the application.
We are scheduled to go live end of this week with new version but QA and beta testers are pretty pleased with what they are seeing in terms of performance improvement.
Will keep you posted.
