[news.eclipse.dsdp.ercp] Re: eRCP evaluation for graphics

[Gorkem Ercan <gercan@xxxxxxxxxxxxxxx>]

I do not have any numbers that I can publish for performance comparison. 
However, the performance of the UI components should be comparable with 
the native components. Our aim with the GC and custom drawing on S60 
was to perform enough for custom widgets and business graphics. Although 
we did bit better than that, I think we still have room to improve. In 
means of memory, eSWT is not that much different than any other Java 
application. However, eSWT has some big components like Browser that 
will naturally have larger memory consumption.

>Is there any work being done to support OpenGL ES in eSWT?
	Not currently, but I think OpenGL can be the next logical step to 
support in eSWT.
