Hi all,
This may all be an old news to you, but it was pleasant surprise for me.
I have always used two major browsers: FF and IE.
I must say that comparing FF3 and IE7 by using ExtJS, their JS engine performance is similar. You can see a lag when resizing extjs form with many elements including grids, initializing JS code, etc.
Recently I have been reading some posts about Safari 3.1 and its JS engine being super fast. I just installed it and I was fascinated. Running my test extjs app in safari 3.1 leaves FF3 and IE7 far behind. It is snappy, fast, responsive, renders almost instantly... almost like a real desktop app or even better (considering some desktop apps these days). I was very much positively surprised. Even more, as I read they are building even better JS engine (squirrelfish) which is said to be 1.5x faster then current one.
I also read there are problems with safari and so on, but so far I didn't find any.. using my test ExtJS app that is.
Well, I hope FF and IE will also drastically improve their JS engines soon.
