difference between draw/push and write functions

Unlike the draw/push functions, the write functions are not defined by startWrite() , endWrite() . draw/push functions automatically execute startWrite() and endWrite() internally, which makes processing slightly slower when multiple drawings are performed in succession. In such a case, speed can be increased by writing all draw/push functions together between startWrite and endWrite.
