Hi Jean, I think that javascript is not the problem. Look at DOM generated by qooxdoo and you see DIVs in DIVs in DIVS, very, very much DIVS in DIVs :)
We are just using DOM for what it is not created for. Also for example only intelligent container is table, because all others needs to generate very much dom objects to show. For example java applets or silverlight demos are very fast compared to qooxdoo, reason is the GUI framework and (native) GUI features thay can use (not creating DOM for every list item, tree item, column, etc, just write onpaint handler and go). For example try qooxdoo in Google Chrome, it has very fast javascript, but application is not faster compared to Firefox, because DOM manipulation and rendering is expensive. So, native client is interesting plugin (I tried it, I'm C++ developer and C++ is best language for me) but it makes applications totally unportable (source code and binary code too) and probably dangerous. Maybe we can use <canvas> in the future to write onpaint handlers for list items, it can be interesting to get something like this to work :) Cheers - Petr 2008/12/11 Jean-Baptiste BRIAUD -- Novlog <[email protected]>: > Hi, > > I'd like to share some "R&D discussion" around Native Client from > Google. > http://code.google.com/p/nativeclient/ > > Javascript look too slow ?
