For GTK+, being +performant does not only mean "paint widgets fast". It also means +things like the time needed to set up widgets, to map and draw a +window for the first time, and emitting/propagating signals. + +The following is accurate as of 2005/07/26. + + +Using the framework +------------------- + +Right now the framework is very simple; it just has utility functions +to time widget creation, drawing, and destruction. To run such a +test, you use the functions in timers.h. You can call this: + + timer_time_widget (create_func, report_func, user_data); + +You must provide the create_funcn and report_func callbacks. + +The create_func: + + This simply creates a toplevel window with some widgets inside it. + It is important that you do not show any of the widgets; the + framework will call gtk_widget_show_all() on the toplevel window + automatically at the right time. + +The report_func: + + This function will get called when timer_time_widget() reaches an + interesting point in the lifecycle of your widget. See timers.h and + the TimerReport enumeration; this is what gets passed as the + "report" argument to your report_func. Right now, your function + will be called three times for each call to timer_time_widget(): + + 1. With report = TIMER_REPORT_WIDGET_CREATION. A timer gets + started right before timer_time_widget() calls create_func, + and it gets stopped when your create_func returns. This + measures the time it takes to set up a toplevel window (but + not show it). + + 2. With report = TIMER_REPORT_WIDGET_SHOW. A timer gets started + right before timer_time_widget() calls gtk_widget_show_all() + on your toplevel window, and it gets stopped when the window + has been fully shown and painted to the screen. + + 3. With report = TIMER_REPORT_WIDGET_DESTRUCTION. A timer gets + started right before timer_time_widget() calls + gtk_widget_destroy() on your toplevel window, and it gets + stopped when gtk_widget_destroy() returns. + +As a very basic example of using timer_time_widget(), you can use +something like this: + +---------------------------------------------------------------------- +#include +#include +#include "timers.h" + +#define ITERS 20 + +static GtkWidget * +create_cb (gpointer data) +{ + GtkWidget *window; + + window = gtk_window_new (GTK_WINDOW_TOPLEVEL); + /* ... fill the window with widgets, and don't show them ... */ + + return window; +} + +static void +report_cb (TimerReport report, gdouble elapsed, gpointer data) +{ + const char *type; + + switch (report) { + case TIMER_REPORT_WIDGET_CREATION: + type = "widget creation"; + break; + + case TIMER_REPORT_WIDGET_SHOW: + type = "widget show"; + break; + + case TIMER_REPORT_WIDGET_DESTRUCTION: + type = "widget destruction"; + break; + } + + fprintf (stderr, "%s: %g sec\n", type, elapsed); +} + +int +main (int argc, char **argv) +{ + int i; + + gtk_init (&argc, &argv); + + for (i = 0; i < ITERS; i++) + timer_time_widget (create_cb, report_cb, NULL); + + return 0; +} +---------------------------------------------------------------------- + + +Getting meaningful results +-------------------------- + +Getting times for widget creation/drawing/destruction is interesting, +but how do you actually find the places that need optimizing? + +Why, you run the tests under a profiler, of course. + +FIXME: document how to do this. + + +Feedback +-------- + +Please mail your feedback to Federico Mena-Quintero . +This performance framework is a work in progress. diff --git a/perf/appwindow.c b/perf/appwindow.c new file mode 100644 index 000000000..6230c91dc --- /dev/null +++ b/perf/appwindow.c @@ -0,0 +1,423 @@ +/* This file contains utility functions to create what would be a typical "main + * window" for an application. + * + * TODO: + * + * Measurements happen from the start of the destruction of the last window.
