Execution-Time Benchmarks Report ⏱️Execution-time results for samples comparing the following branches/commits: Execution-time benchmarks measure the whole time it takes to execute a program. And are intended to measure the one-off costs. Cases where the execution time results for the PR are worse than latest master results are shown in red. The following thresholds were used for comparing the execution times:
Note that these results are based on a single point-in-time result for each branch. For full results, see the dashboard. Graphs show the p99 interval based on the mean and StdDev of the test run, as well as the mean value of the run (shown as a diamond below the graph). gantt

Summary of changes
Splits the
build_macos
stage into 2 jobs and runs them in parallelReason for change
The
build_macos
job is slow, over-an-hour slow. And it's a prerequisite for thedd-trace
tool build, which is in turn a prerequisite for the tool artifact tests and the tool installer tests.Implementation details
Similar to how we had to do with the linux tracer (though we didn't parallelise there currently, we could consider it). Splits the build into two separate jobs:
We then add a third job that recombines the artifacts to give the same "existing" artifacts as we currently produce, namely the tracer home
and the "current build directory"I didn't bother downloading the whole mac directory and re-uploading it in the end. As the macos unit tests are the only place we need this currently, just re-downloading them there insteadTest coverage
If it works, we're good
Other details
Even with this, the stage is still the slowest build stage by a factor of 2, but I'm not sure there's much more we can do to improve that.
