Jamie Madill 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.

Yuly Novikov b8d2664f 2017-10-27T18:14:14 Run angle_perftests on GLES backend Adds OPENGLES_NULL configuration and selects between OPENGL and OPENGLES based on whether building for Android. Also 2 small changes to get the newly enabled tests to pass on N5X: 1. Require GL_EXT_texture_storage in TexSubImage test 2. Limit numVertexUniforms and numFragmentUniforms to 64 in MatrixUniforms test BUG=675997 Change-Id: I5439e5fb7e93b3a928f12594761115d56f60d81b Reviewed-on: https://chromium-review.googlesource.com/748522 Commit-Queue: Yuly Novikov <ynovikov@chromium.org> Reviewed-by: Jamie Madill <jmadill@chromium.org>
Olli Etuaho 465b3a5f 2015-12-15T12:08:24 Add texture sampling perf test The test generates a texture containing random data and then blurs it in a fragment shader using nearest neighbor sampling. The test is specifically designed to test overhead of GLSL's builtin texture*() functions that may result from how ANGLE translates them on each backend.
