In my own tests, using the built-in GUI windows I get the following numbers on the simple_plot_fps.py speed test (which essentially tests redrawing speed, which is pretty GUI-backend dependent, as opposed to the first drawing operation which involves more common code):
GtkAgg: wallclock: 3.73636507988 user: 2.9 fps: 26.7639799276 Gtk: wallclock: 1.99883008003 user: 1.99 fps: 50.0292651181 TkAgg: wallclock: 4.55140709877 user: 4.41 fps: 21.9712273216 So you can see that GtkAgg is actually slightly faster than TkAgg, and Gtk (if you can accept the lower rendering quality), is almost 2x as fast. So, if you're certain the same amount of data is being plotted in the default Tk window and your custom Gtk window, it seems to suggest that the slowdown is probably something in how you're embedding it. (Obviously the number of data points as a significant impact on speed regardless of backend.) I'm not enough of a Gtk expert that anything in what you're doing jumps out at me. What triggers the call to "plotFrictionProfile?" Is that possible that is getting called more times than you expect?
