This directory contains a collection of traces that represent applications in the wild. In particular, they represent behaviour that someone thought worthy of further study and analysis! To capture a trace: $ cairo-trace --profile application [args...] This will produce a application.$pid.lzma file. If you think it is interesting add it to this repository, giving it a short but descriptive name, and add a note here explaining what the trace captures. To replay traces: Use cairo/perf/cairo-perf-trace. By default cairo-perf-trace will loop over all traces within cairo/perf/cairo-traces for all test targets. To run against a subset specify a series of traces on the command line and use the CAIRO_TEST_TARGET environment variable to filter the target. For example, CAIRO_TEST_TARGET=xlib ./cairo-perf-trace firefox. Guidelines ---------- Initial thoughts... 1. Nothing obscene, or otherwise unsuitable for viewing by children or in the workplace - please be considerate to others. The trace should also respect copyright where appropriate. Even though the content is not usually visible during a replay, it is not acceptable to distribute such material via freedesktop.org. 2. Each trace must be "representative of a significant use". The goal is a set of traces that capture the behaviour of real applications during active sessions. (We must guard against the tests becoming too artificial as that is better served by purpose-written micro-benchmarks.) 3. For practical reasons (i.e. continuous performance testing), each trace should neither be profligate in the resources consumed nor the duration of the run. However, I'm loathe to exclude tests simply because they take too long or can not be run on tiny machines. (Instead, I plan to create subset of tests that have been truncated to run within 60s on a 2GHz Intel Core2.) 4. If the application significantly improves such that the current trace is no longer representative of that application, it must be replaced. This is to ensure that we do not try to optimise for "historically broken behaviour".

It appears the cairo backend is not very mature... gnome-system-monitor-20090821 - A clean cairo version of gnome-system-monitor, graphing CPU/memory/network activity whilst reading the news with epiphany. Benchmarks ---------- The benchmarks are a set of trimmed traces that should run in a reasonable timeframe (I'm aiming for <10 seconds on a 2GHz Core2 with cairo-image, using ./csi-trace --trim=10). The idea here is that this allows us to quickly determine a representative metric without running the whole suite -- and is useful for the casual user. The full traces are kept as they will exercise corner cases much more thoroughly and are not compromised by the conversion. To run the benchmark subset, use cairo-perf-trace benchmark. firefox-talos-gfx - The synthetic firefox benchmark (identical to firefox-talos-gfx-20090702) that exercise the core renderer. firefox-talos-svg - The synthetic firefox benchmark (identical to firefox-talos-svg-20090702) that exercise the SVG renderer. firefox-planet-gnome - Scrolling the full height of http://planet.gnome.org/ firefox-fishtank - A HTML5 canvas demo, courtesy of http://ie.microsoft.com/testdrive/Performance/FishIETank/Default.html This is a sprite based animation, and mostly tests the performance of unaligned, scaled alpha blits. firefox-fishbowl - A HTML5 canvas demo, courtesy of http://ie.microsoft.com/testdrive/Performance/fishbowl/Default.html A slightly more complex fishtank. firefox-paintball - A HTML5 canvas demo, courtesy of http://ie.microsoft.com/testdrive/Performance/Paintball/Default.html firefox-particles - A HTML5 canvas demo, courtesy of http://ie.microsoft.com/testdrive/Performance/ParticleAccelration firefox-chalkboard - Another HT|ML5 canvas demo written by Microsoft to demonstrate their own virtues by highlighting poor performance elsewhere. http://ie.microsoft.com/testdrive/Performance/Chalkboard firefox-canvas - A pair of synthetic canvas benchmarks, found in the wild firefox-canvas-alpha at http://flashcanvas.net/examples/dl.dropbox.com/u/1865210/mindcat/canvas_perf.html firefox-asteroids - A HTML5 game benchmark, http://www.kevs3d.co.uk/dev/asteroidsbench/ firefox-scrolling - A bug report concerning an ancient performance regression http://home.arcor.de/bazonbloch/scrolltest/whyisscrollingonlinuxslowerthanonwindows.htm gvim - Scrolling within a window showing a UTF-8 document gnome-terminal-vim - The same test but using vim inside a gnome-terminal, but repeated more often to give a comparable time. evolution - based on full/evolution-20090607 gnome-system-monitor - based on full/gnome-system-monitor-20090821 midori-zoomed - scroll http://www.jakob-persson.com/styles_demo/?s=5 whilst zoomed in. ocitysmap - ocitysmap-render -f png -c Sanguinet popper - based on full/poppler-20090811 poppler-reseau - A vector based map of a French city, which is abnormally slow in cairo: https://bugs.freedesktop.org/show_bug.cgi?id=38927 swfdec-giant-steps - based on full/swfdec-giant-steps swfdec-youtube - based on full/swfdec-youtube xfce4-terminal-a1 - scrolling 'man gcc' using the terminus font grads-heat-map - provided by Jennifer Adams, a typical output from GraDS, an open-source program for the analsyis and display of meteorlogical data.
