Carl Worth, performance, GtkPerf

Carl Worth blogged here about Cairo 2D performance measurements:
Various attempts at 2D-rendering benchmark suites have appeared and even become popular. Notable examples are x11perf and gtkperf. My claim is that these tools range from useless to actively harmful when the task is understanding performance of real applications.

Unfortunately, the workload of things like x11perf and gtkperf rarely come close to simulating practical workloads.
Should I be offended and sad as someone as respected as Carl blames my precious GtkPerf? Well of course not! Citing myself from GtkPerf website:
I know that bencmarking tools (including GtkPerf) can be fooled and don't give real-life results. Yet, I belive that GtkPerf can be helpful to solve for example this kind of things:
...

So as seen, I fully agree (and have always agreed) that GtkPerf is not the tool to use for getting real-life application performance measurements. But what it is, is a very easy and fast way to get a view of the GTK+/GDK/C…
