There was a problem hiding this comment. is it worth splitting this by each matcher to parallelize the runs and reduce the runtime even more ? There was a problem hiding this comment. If you go this route, you would be able to get away with building a HashMap of rule-matchines during setup() and then return pass the machine during load tests. It'll reduce the number of scaffolding classes for benchmarks. There was a problem hiding this comment. This grouping is done not for parallelism, parallelizing these benchmark on the same box is a bad idea because the results will be noisy. The reason for this grouping is to have different setup for different benchmarks: for simple ones it is 40 seconds warmup + 50 seconds measurement, for complex ones it is 2 minutes warmup + 3 minutes measurement just because every call for complex benchmarks takes much longer. We could split across multiple boxes for parallelism, but I don't think it is worth the effort and probably would be harder to collect results. What we actually want to do regarding parallelism is to run every benchmark by 2 threads (and check that throughput is ~2x of 1 thread) to make sure that we don't have any contention or false sharing. Right now these benchmarks are single threaded and thus we don't actually know if we have an issue. I will push this change. |

This is kept because we haven't moved everything yet?

I have ported everything from
CL2Benchmarkbut notCL2NoCompileBenchmark. Not sure if it is actually an important use case.There was a problem hiding this comment.

They are important so I'm happy to have "Run Benchmarks" step still until these tests that check for rule building, memory usage, et all.
