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:
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). gantt

Summary of changes
Fixes more flake in the IIS smoke tests
Reason for change
A recent WAF rules update #7331 started adding more tags to spans, which ultimately can cause flake. Additionally, there are other tags which are only added to the very first span generated, but in a race-y way, so that can cause flake
Implementation details
Add more exclusions to the smoke tests in general. I signed off on these exclusions with ASM (they suggested it!)
Test coverage
If the tests pass, we're good
