2009-09-15[perf] Reorganise cairo-perfChris Wilson1-49/+0
In preparation to creating a new hub to control performance measuring and reporting, move the current cairo-perf out of the way.
2009-08-29[perf] Match directory namesChris Wilson1-1/+1
In order to handle 'cairo-perf-trace benchmark', we need to perform the can_run? test on the directory name as opposed to the individual trace names. Make it so.
2009-08-06[perf] Calibrate tests to run for at least 2 secondsChris Wilson1-2/+3
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.
2009-02-13[perf] Split can_run? into a separate precondition.Chris Wilson1-0/+3
Allow tests to skip unnecessary setup when pruning the list of perf cases.
2007-04-25perf: Add new paint-with-alpha testCarl Worth1-0/+45
MacSlow noticed that cairo_paint_with_alpha is much slower than it should be, (and jrmuizel has a nice plan for fixing the performance bug).
