The good points:
Predictably Opera was the fastest to load and stayed low on CPU usage when viewing Flash rich pages, although the problems it still has viewing some webpages properly might put people off.
A resource friendly surprise was GreenBrowser as it loaded fast, was low on memory and kept CPU usage to a minimum. The interface is not the best, but compatibility should be good as it uses the Internet Explorer Trident rendering engine.
Firefox has improved a lot recently in resource usage, but few people run it without plug-ins so the memory usage and load time will likely increase when several are added.
The not so good points:
Avant’s nice idea of 3 different switchable browser engines in the same browser sounds like a good idea, but needs a lot more work to make it fully optimized and really worth using.
It’s not clear if Apple have discontinued Safari, but with it’s high memory usage in this test and terrible load time of the 10 test pages, I’m not sure why anyone would want to use it.
High memory and CPU usage playing Flash meant Chrome surprisingly wasn’t great either, which is probably why they’re concentrating on these areas in future versions.
