build-perf-diagnostics
dotnetFind the slowest parts of every build.
build performance
What it does
Diagnoses MSBuild build-performance bottlenecks through binary-log performance analysis.
When to use it
Use after build-perf-baseline establishes measurements; do not use for initial baselines, incremental-build fixes, parallelism tuning, or non-MSBuild systems.
How to use it
Give it a project build; it generates a binlog and returns a performance diagnosis based on target, task, analyzer, and node metrics.
What you provide
- a slow MSBuild build
- An existing project

No additional actions listed in the analysis.
What you need · 3
The dotnet command must be available to generate the build binary log and run MSBuild replay commands.
The workflow is intended to run after build-perf-baseline has established measurements.
The binlog MCP server enables the primary analysis flow; the text-log replay flow is documented when it is unavailable.
