It won't be fast.
Pixel operations in BM have to be done on pixmaps.
Those are either drawn to backbuffer (-> pixel per pixel copy) or have to be made an image which means texture generation and upload
In both cases, not fast enough to be "ten times faster" than anything done yet.
if you need it to be faster, check out shaders and do it as pixel shader for example.
