Hi Andrew, Yes, I've tried the printf thing. It takes about 1.5 sec. Very strange.

Is it normal for there to be a 1.5 sec delay, or have I bumbled > something? While there is some cost to spinning up a new thread, it should be a much much less than 1.5 seconds. I suspect the problem may be elsewhere; what precisely is "something noticeable"? Are you creating or modifying GTK elements in your new thread? All GUI operations have to be done on the main thread (e.g. thread with the GMainLoop). Try putting a printf() at the start of your new thread; does that take 1.5 seconds to show up on stdout? _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
