Add more cleanup to benchmarks #7865

andrewlock · 2025-11-26T08:04:37Z

Summary of changes

Update the JetBrains SelfApi package to latest version
Don't run background tasks like remote config, telemetry, discovery service in benchmarks
Cleanup "global" tracers after benchmark

Reason for change

Benchmarks should be isolated to keep them consistent, but unfortunately a lot of our code has Tracer.Instance and Security.Instance scattered around. That means we need to set up global state for some of the benchmarks. Currently, we're never cleaning up that global state, which could introduce variance (flake) in the benchmarks).

Similarly, new Tracer instances start a bunch of background tasks, such as remote configuration, telemetry, discovery service. These all have the possibility of skewing results and introducing flake.

Implementation details

Cleanup any resources (e.g. Tracer instances, but anything disposable) in [GlobalCleanup]
Ensure we remove and replace the global Tracer instances in cleanup
Disable services that start background jobs (discovery service, telemetry, remote config)
Create a helper for creating a tracer with default benchmarking configuration

Test coverage

This is the test - we may see some variation from the current results, but hopefully the results will be more stable subsequently

Other details

I wish we could not use Tracer.Instance (or Security.Instance, or Iast.Instance) at all. It would make all of this much easier to reason about and reduce the chance of accidental cross-talk. That's something we'll move towards slowly, for now this is probably the best we can do.

Comparison explanation

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 highlighted in **red**. The following thresholds were used for comparing the execution times:

Welch test with statistical test for significance of 5%
Only results indicating a difference greater than 5% and 5 ms are considered.

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).
