How does WebGL compare to a native application?



It depends strongly on the specific application. The actual GL calls themselves, once data is on the GPU, execute at the same speed as in native applications, because it's the same hardware/drivers/API. But, the roundtrips between JS code (and JS datatypes) and the GPU could kill performance even more than CPU<->GPU roundtrips normally do. So depends on how good the application is at avoiding those.
