Benchmarks

Benchmark execution time: 2026-08-05 15:07:33

Comparing candidate commit e7443a4 in PR branch v6.9.0-proposal with baseline commit 92d2ec1 in branch v6.x.

📊 Benchmarking dashboard

Found 0 performance improvements and 0 performance regressions! Performance is the same for 2316 metrics, 42 unstable metrics.

Explanation

This is an A/B test comparing a candidate commit's performance against that of a baseline commit. Performance changes are noted in the tables below as:

• 🟩 = significantly better candidate vs. baseline
• 🟥 = significantly worse candidate vs. baseline

We compute a confidence interval (CI) over the relative difference of means between metrics from the candidate and baseline commits, considering the baseline as the reference.

If the CI is entirely outside the configured SIGNIFICANT_IMPACT_THRESHOLD (or the deprecated UNCONFIDENCE_THRESHOLD), the change is considered significant.

Feel free to reach out to #apm-benchmarking-platform on Slack if you have any questions.

More details about the CI and significant changes

You can imagine this CI as a range of values that is likely to contain the true difference of means between the candidate and baseline commits.

CIs of the difference of means are often centered around 0%, because often changes are not that big:

---------------------------------(------|---^--------)-------------------------------->
                              -0.6%    0%  0.3%     +1.2%
                                 |          |        |
         lower bound of the CI --'          |        |
sample mean (center of the CI) -------------'        |
         upper bound of the CI ----------------------'

As described above, a change is considered significant if the CI is entirely outside the configured SIGNIFICANT_IMPACT_THRESHOLD (or the deprecated UNCONFIDENCE_THRESHOLD).

For instance, for an execution time metric, this confidence interval indicates a significantly worse performance:

----------------------------------------|---------|---(---------^---------)---------->
                                       0%        1%  1.3%      2.2%      3.1%
                                                  |   |         |         |
       significant impact threshold --------------'   |         |         |
                      lower bound of CI --------------'         |         |
       sample mean (center of the CI) --------------------------'         |
                      upper bound of CI ----------------------------------'

Unstable benchmarks

These benchmarks have a confidence interval too wide to call a change; treat them as noise rather than signal.

More details

Focused execution found no clear behavioral regression attributable to this release diff. The expanded Test Optimization validation paths, loader matcher, AppSec channel split, worker telemetry rules, and configuration handling passed targeted checks; PG and LLMObs runtime suites could not fully start because local version fixtures and the test agent processor were unavailable.

Settle the Cucumber coordinator callback on rejection

In the Cucumber 7 parallel coordinator path, this adapts a callback-based run(numberOfWorkers, done) API but only invokes done when wrappedStart fulfills. If the setup path or underlying coordinator rejects before invoking its callback, the returned promise is not enough for the callback-based caller and done is never called, which can leave the parallel run hanging and skip the Test Optimization flush. Please invoke the callback from both fulfillment and rejection paths.

Preserve the OTel source tag on feedback submissions

When DD_TRACE_OTEL_ENABLED is true and feedback is attached to an OTel-created span or trace, this builds the feedback tags without the OTel flag that submitEvaluation passes to the same helper. Without source:otel, the backend is not told to wait for OTel span conversion, so feedback submitted against those span or trace IDs can arrive before the converted span is available and fail to associate; pass this._config.DD_TRACE_OTEL_ENABLED here as well.
