My experience is the opposite, on my particular linux box I get the worst
performance with legacy (it is fast for tiny toy boards, but the
performance rapidly declines as it gets more complicated), New Cairo is
also slow but not as bad, but the absolute best performance is with OpenGL
(of course). And I feel it could be even better if it wasn't stuck on
OpenGL from 2006, heck if it could use GLES/GL3 it would run on the
raspberry pi 3!
