Summary of changes

Skips a few errors that are Ignored in Error Tracking and shouldn't really be sent to telemetry as we can't act on them.

Reason for change

Nothing we can really do about these.

Implementation details

Marked as ErrorSkipTelemetry

Test coverage

N/A

Other details

I guess one thing we do lose here is whether we want to see how often these happen?

@tonyredondo is this actually an error, or should it just be a warning? (ErrorSkipTelemetry is obvs fine for now, unless we hear otherwise)

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).
