  • 💬 PR Avoid unconditional NUL-escape allocation in TestContext.Write/WriteLine #11084 (NUL-escape allocation "fix" from prior run) was closed by maintainer: verified string.Replace doesn't allocate on no-match even on .NET Framework 4.8, so the change was a net regression (redundant scan).

Performance Opportunities Backlog

  1. PrivateObject.Helpers.cs BuildGenericMethodCacheForType (net-framework-only): rebuilds cache per PrivateObject instance construction, not cached across instances of the same type. Medium risk (touches internal representation), low priority.
  2. TestExecutionManager.ParallelExecution.cs: wraps each single test element into a new array per test when building parallel scheduling chunks. Inherent to the chunk-representation contract; medium risk/effort to redesign.
  3. AggregatedConfiguration indexer scan: linear provider scan per config lookup, results already memoized. Low impact.
  4. ServerTestHost.RequestExecution.cs: .Select().ToArray() on test nodes, once per run request (not per-test). Low impact.
  5. RetryArtifactProcessor.cs: GroupBy/Any(Count()) double-enumeration, only matters with many retries+artifacts. Low volume.
  6. RetryOrchestrator.ArtifactRecovery.cs: Any() per-manifest-line. Low volume.
  7. InheritedMemberFromDifferentMSTestVersionAnalyzer.GetFrameworkAssembly/IsGloballyVisibleReference: LINQ chain over GetAttributes() and compilation.References.Any(...) scan run for every named-type symbol in a compilation (IDE/build hot path in the analyzer sense), before cheaper early-out checks. Low confidence this is measurably costly (collections involved are small; empty-attribute classes short-circuit), not prioritized without profiling evidence.

Codebase remains thoroughly optimized after ~6 weeks of near-daily scans across virtually every module (Platform, Adapter, TestFramework, Analyzers, Extensions). Backlog items above are all low-priority/low-confidence; several are inherent to design and considered won't-fix without a larger redesign.

Discovered Commands

./build.sh                              # restore + build (Debug)
./build.sh -test                        # build + unit tests
./build.sh -pack                        # produce NuGet packages
./build.sh -pack -test -integrationTest # full suite (slow)

Note: MSTestAdapter.UnitTests and other net48-targeting tests can't run standalone in this Linux sandbox (no .NET Framework SDK); full ./build.sh -test is the reliable path.
