SVG performance in IE (since IE9) has really been and is stellar, indeed. Chrome caught up mostly by now and at least at work the difference between Chrome and IE for certain tasks is that Chrome spends more time rendering and IE spends more time JavaScripting. Firefox SVG performance has been disappointing, mostly and mobile browsers are often better off with canvas as well since performance is generally constrained there. SVG performance in IE doesn't date back to VML, though. They just made hardware-accelerated rendering a major feature of their browser back then, while no one else was doing it properly. Similar to how Chrome started with JITting JavaScript to make it fast and everyone else caught up on that afterwards.
