Benchmarks

Benchmark execution time: 2026-08-21 11:05:54

Comparing candidate commit 1be66be in PR branch v6.12.0-proposal with baseline commit df15b02 in branch v6.x.

📊 Benchmarking dashboard

Found 9 performance improvements and 0 performance regressions! Performance is the same for 2287 metrics, 14 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 ----------------------------------'

[datadog-prod-us1-4]

Collection values with many custom properties can still make debugger log messages grow without a limit. This bypasses the new property limit.

[datadog-prod-us1-4]

Limit custom properties on collection values

A probe can create a large debugger log message and a large temporary allocation.

Assertion details

• Input: A template expression returns an array, typed array, or similar collection with many custom enumerable properties.
• Expected: The formatter must limit both collection elements and custom enumerable properties.
• Actual: The collection branch calls util.inspect with maxArrayLength. This option limits array elements but does not limit custom enumerable properties.
