Summary of changes

Update the tag list generator to always use ReadOnlySpan<byte> properties instead of byte[]

Reason for change

After moving our vendored Span<T> implementation into the System namespace, various optimizations open up to us, including using ReadOnlySpan<byte> properties on .NET Framework instead of static readonly byte[] to avoid startup costs.

Implementation details

Replace the code generated by the generator, and update the generated code

Test coverage

Covered by snapshot tests and behaviour is covered by existing tests. We'll check the benchmarks to make sure that we don't see any perf impact (there shouldn't be, impact should just be reduced startup costs)

Other details

Depends on a stack updating our vendored system code

Benchmarks

Benchmark execution time: 2026-04-21 11:24:15

Comparing candidate commit 54730c9 in PR branch andrew/update-tag-generator with baseline commit b821c57 in branch master.

Found 0 performance improvements and 0 performance regressions! Performance is the same for 27 metrics, 0 unstable metrics, 87 known flaky benchmarks.

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 ----------------------------------'
