Chris Wilson	0db9e010fa	[perf] Calibrate tests to run for at least 2 seconds ... By ensuring that tests take longer than a couple of seconds we eliminate systematic errors in our measurements. However, we also effectively eliminate the synchronisation overhead. To compensate, we attempt to estimate the overhead by reporting the difference between a single instance and the minimum averaged instance.	2009-08-06 10:15:40 +01:00
Chris Wilson	655f698733	[perf] Split can_run? into a separate precondition. ... Allow tests to skip unnecessary setup when pruning the list of perf cases.	2009-02-13 13:26:53 +00:00
Chris Wilson	3a45b07af9	[perf] Free images for composite-checker ... Fix memleak of the image surfaces.	2008-10-20 23:04:03 +01:00
Björn Lindqvist	f644d78dc1	[perf] Add composite performance test. ... Add a new test case to Cairo for checking the performance of Cairo's equivalent to GDK's gdk_pixbuf_composite_color() operation. That is an operation that happens to be extremely useful when viewing or editing transparent images so I think it is important that it is as fast as possible.	2008-10-08 20:10:27 +01:00
