Add performance tests for GObject primitives These are basic performance test for a couple of basic gobject primitives: * construction of simple objects. Simple is a bare gobject derived class with no properties, signals or interfaces. * construction of complex objects. Complex is a gobject subclass with construct properties, normal properties, signals, and implements an interface. * run-time type check of complex objects * signal emissions Lots of care is taken to try to make the results reproducible. Each test is run for multible "rounds", where we try to make each round be "not too short" in order to be significant wrt timer accuracy, but also "not to long" to make the probability of some other random event happening on the system (interrupts, other process scheduled, etc) during the round less likely. The current target round time is 4 msecs, which was picked without rigour, but seems small wrt e.g. scheduler time. For each test we then run the calculated round size for 60 seconds, and then report the performance based on the minimal time of one round. The model here is that any random stuff that happens during a round can only slow it down, there is nothing that can make it go faster, so the minimal time is the best estimate of how fast one round goes. The result is not ideal, even on a "idle" system the results vary from round to round, but the variation seems to be less than 1%. So, any performance difference reported by this test over 1% is probably statistically significant. Additionally the tests can be run with or without threads being initialized. The script tests/gobject/run-performance.sh makes it easy to produce a performance report for the current checkout. https://bugzilla.gnome.org/show_bug.cgi?id=557100 2009-08-20 14:34:51 +02:00			`#!/bin/sh`
