Performance 1.8.8.., xlib

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.

So it’s been a while. It seems I’m not a natural blogger — especially when other people describe my work far better than I do myself, thanks Carl!

Adding pretty pictures to memfault

After seeing Vlad’s pretty pictures for firefox’s fragmentation, I wanted some of that bling for myself. Hence the development of a prototypical GUI for memfault, a valgrind memory profiler ala massif.
