I assume you are using VMWare, on VBE we already have a more optimised version which copies the memory in lines. The best speed up for VMWare would be to also add an implementation to SVGACanvas/Driver which draws lines of image at once by copying between the memory locations directly.

The best way would be to use the MemoryOperations.Fill

This should be fixed in the devkit #1959
