You've clearly put a lot of effort into measuring things. And thanks
for sharing the table of results you've got so far.

But can you also share the actual profiles you've generated, and
perhaps the benchmark code you've got. That should help us quite a bit
in actually seeing what's happening.

Meanwhile, what cairo backend are you using? Are you targeting the X
Window System, for example?
