A small application to benchmark and crash test GTK themes: the "GTK

Theme Torturer" [1]. It was first aimed at testing and profiling the

OLPC theme, but it was designed to test and make all GTK

themes/engines suffer. A lot.

Everybody loves screenshots, so here they come first:

http://wiki.laptop.org/go/GTK_for_OLPC#GTK_theme.2Fengine_torturer_and_crash_tester

It mainly does two things:

* For each of the most common widget types [2],

redraw/resize/create/destroy the widget many, many times (you can

adjust the number of iterations with the "Torture level" slider, hin,

hin). The torturer will provide, for each widget type, a detailed

report of time measures it has done (thanks to Federico's widget

profiler infrastructure) for widget creation, mapping, expose, etc.

With this torture test, it is also easy to detect memory leaks since

the widgets are created/destroyed lots and lots of times.

* Call each of the existing GTK paint functions (which the engines

implement themselves) with unusual parameters (and even, with all

queerly possible weird combinations of strangely unusual parameters),

to make the engine crash. Of course, the report is detailed enough so

that you can see which set of parameters caused the crash, if any.

A report was posted (sent to people at OLPC [3] and Ubuntu [4]) with

benchmarks of several GTK themes: OLPC, Clearlooks, Human (Ubuntu's)

and HighContrast. The benchmark itself is available as a spreadsheet

[5]. It has time measures and ratios between themes; see also the two

emails ([3] and [4]) for a short analysis.

say "GTK Performance List".
