Hi,

...

I like the modernized look, but imo it still misses the simplistic feel. I've had a few people complain that it's hung their whole browser because of the amount of javascript, I didn't proceed to question why because they were VMware fan boys and I simply could never replicate it.

Yes, the admin portal's JavaScript hangs the browser frequently, at least on FF. On Chrome it happens less, but it still happens.

Well, the GUI was built with "browser as application platform" idea in mind so we assume users have a decent web browser, i.e. IE9+ or recent Firefox/Chrome. Indeed, the technology/SDK we use for GUI (Google Web Toolkit) tends to generate lots of JavaScript. At the same time, GWT makes best attempt to produce optimized output and we make best attempt to lazy-load parts of the web application as the user clicks his (her) way through the GUI. One major source of big JavaScript footprint is shared (Java) code between client and server. This is meant to go away as we plan to move GUI on top of REST API, replacing today's GWT RPC mechanism. So things might get better in future with regard to that. Note that web browser's JavaScript/rendering engine performance is not everything, there are also things like browser plugins or HW specs that might slow things down.

Cheers, Martijn. _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
