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
M Joonas Pihlaja	8ec58113df	[perf] Explicitly test rendering a path with lots of intersections. ... We don't have one just for this purpose. The only other path with many intersections that gets actually rendered is zrusin-another, but that might be sped up in the future (say by identifying collinearities up front or something like that.)	2008-12-06 13:21:44 +02:00
