It's a shame that 280 Slides is no longer online, because I'd love to be able to challenge your performance assertion. Back when we released it, in 2008, browsers were a hell of a lot slower than they are now. And even then, 280 Slides launched faster than PowerPoint or Keynote on our machines, and had comparable runtime performance with manipulating objects on the slide. Of course, we did not have many of the most resource intensive Keynote features like 3D animations, but I don't think that's what you meant.
