	3402d523	2018-10-30T15:14:52		Try to reduce variance in angle_perftests. This change does a few things: - make perf test runner script print % variation instead of stddev This makes it a bit more clear how much variance there is. - stabilize CPU in the render perf tests Setting a thread affinity and priority should stop from switching cores during the run. Hopefully can prevent background noise from changing the test results. - warm up the benchmark with a few iterations This should hopefully make the test results a bit more stable. - output a new normalized perf result value The new result is normalized against the number of iterations. So it should hopefully be stable even if the number of iterations is changed. - increases the iteration count in the draw call perf tests. These tests were completely dominated by SwapBuffers time. Increasing the iterations per step means we actually are bottlenecked on CPU time instead.
