Benjamin Bannier reassigned MESOS-8835:
---------------------------------------
Assignee: Benjamin Bannier
> mesos-tests takes a long time to execute no tests
> -------------------------------------------------
>
> Key: MESOS-8835
> URL: https://issues.apache.org/jira/browse/MESOS-8835
> Project: Mesos
> Issue Type: Bug
> Components: test
> Reporter: Benjamin Bannier
> Assignee: Benjamin Bannier
> Priority: Minor
>
> Executing {{mesos-tests}} takes substantially more time than running
> {{stout-tests}} or {{libprocess-tests}} when no tests are executed, e.g., for
> a release build with debug symbols
> {noformat}
> _|master⚡ ⇒ GTEST_FILTER= hyperfine --warmup=3
> ./3rdparty/stout/tests/stout-tests
> ./3rdparty/libprocess/src/tests/libprocess-tests ./src/mesos-tests
> Benchmark #1: ./3rdparty/stout/tests/stout-tests
> Time (mean ± σ): 17.1 ms ± 4.3 ms [User: 12.4 ms, System: 4.5 ms]
> Range (min … max): 11.3 ms … 25.1 ms
> Benchmark #2: ./3rdparty/libprocess/src/tests/libprocess-tests
> Time (mean ± σ): 17.2 ms ± 0.2 ms [User: 13.7 ms, System: 4.7 ms]
> Range (min … max): 16.9 ms … 18.0 ms
> Benchmark #3: ./src/mesos-tests
> Time (mean ± σ): 795.4 ms ± 10.5 ms [User: 397.6 ms, System: 79.5
> ms]
> Range (min … max): 784.7 ms … 814.3 ms
> Summary
> './3rdparty/stout/tests/stout-tests' ran
> 1.01x faster than './3rdparty/libprocess/src/tests/libprocess-tests'
> 46.56x faster than './src/mesos-tests'
> {noformat}
> Looking at where time is spent with {{perf}} points to two {{parameters}}
> functions in {{src/tests/resources_tests.cpp}}. These functions construct
> large collections of {{Resource}} when registering
> {{Resources_Contains_BENCHMARK_Test}} and
> {{Resources_Scalar_Arithmetic_BENCHMARK_Test}}, i.e., these functions will be
> executed even if the corresponding test is filtered out.
