@flar Could you have time to have a look at this? Thanks. |

First, this appears to be modifying an existing benchmark. Once a benchmark is added, it should remain stable as its performance history is tracked. If you have new things to benchmark, a new benchmark should be created so that it doesn't interfere with existing metrics. Second, please run A/B tests with more than 1 iteration so that benchmark jank is averaged out. I typically run AB=4. |
Thank you for reply. For the this point, clipper_cache_perf__e2e_summary seems to be a new benchmark so that it doesn't interfere with existing metrics. For the second point, the result of AB=4 also shows that the rasterizer time is reduced, see: {

Please ignore that part of my comment. When I looked at it the other day all I saw was a few changes that updated a file in the macrobenchmarks area - which looked exactly like it was just modifying an existing benchmark. But, I now see that this PR is about adding a new benchmark. I think I was confused by the link in one of the emails taking me to just a single commit in the chain rather than showing me the entire set of code changes. |

@keyonghan did you look over the CI files? |
|
flutter/engine#32899 depends on it, so merge it first. we can revert it later if there is any problem. |

Benchmark for flutter/engine#32899.
The test result shows that it reduced the rasterizer time by using raster cache to replace saveLayer.
