This time I’m comparing the performance of cairo-xlib using the latest intel-gfx drivers for i915. The big news here is that the use of server-side gradients causes a performance regression as opposed to their presumed benefits. In contrast tot the previous table, this show performance as a percentage speedup relative to the first result (in this case normally 1.8.8). This makes the regressions much clearer.
