For the first render of points your numbers seem reasonable. For subsequent renders you will find different tradeoffs on the old backend. Display Lists are typically slower for a first render but faster on subsequent renders. With them turned off the first render is fast but subsequent renders are not any faster. Subsequent renders with OpenGL2 should be fairly fast.
