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:

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).

I think the snapshots need to be updated still

If this passes the system tests I'd be happy to approve after the ! are looked into and reduced

Overall this is looking on track. In order to approve we just need to see updated snapshot files (which may require rebasing on/merging in master) and some small tweaks regarding the nullable checks in the span link mapping.

A bunch of minor comments, but nothing blocking I think 🙂 Nice work 👍

Can this be null, or will it always have a value?

Mmm AFAIK users can't create a link with null context so it should always have a value: https://github.com/dotnet/runtime/blob/main/src/libraries/System.Diagnostics.DiagnosticSource/src/System/Diagnostics/ActivityLink.cs

Thanks!

I still think we need to go through and remove some more null forgiving operators that were added throughout but that can be done in a follow up PR

zacharycmontoya

LGTM, thanks for adding the feature! We should do some cleanup work on the nullability checks, but the feature is doing exactly what it's supposed to, nice work! 🎉
