Without measurements, optimization is guesswork. This skill covers how to establish baselines and apply systematic optimization techniques.\n\n**Related skills:**\n- `build-perf-diagnostics` — binlog-based bottleneck identification\n- `incremental-build` — Inputs\u002FOutputs and up-to-date checks\n- `build-parallelism` — parallel and graph build tuning\n- `eval-performance` — glob and import chain optimization\n\n---\n\n## Step 1: Establish a Performance Baseline\n\nMeasure three scenarios to understand where time is spent:\n\n### Cold Build (First Build)\n\nNo previous build output exists. Measures the full end-to-end time including restore, compilation, and all targets.\n\n```bash\n# Clean everything first\ndotnet clean\n# Remove bin\u002Fobj to truly start fresh\nGet-ChildItem -Recurse -Directory -Include bin,obj | Remove-Item -Recurse -Force\n# OR on Linux\u002FmacOS:\n# find . -type d \\( -name bin -o -name obj \\) -exec rm -rf {} +\n\n# Measure cold build\ndotnet build \u002Fbl:cold-build.binlog -m\n```\n\n### Warm Build (Incremental Build)\n\nBuild output exists, some files have changed. Measures how well incremental build works.\n\n```bash\n# Build once to populate outputs\ndotnet build -m\n\n# Make a small change (touch one .cs file)\n# Then rebuild\ndotnet build \u002Fbl:warm-build.binlog -m\n```\n\n### No-Op Build (Nothing Changed)\n\nBuild output exists, nothing has changed. This should be nearly instant. If it's slow, incremental build is broken.\n\n```bash\n# Build once to populate outputs\ndotnet build -m\n\n# Rebuild immediately without changes\ndotnet build \u002Fbl:noop-build.binlog -m\n```\n\n### What Good Looks Like\n\n| Scenario | Expected Behavior |\n|----------|------------------|\n| Cold build | Full compilation, all targets run. This is your absolute baseline |\n| Warm build | Only changed projects recompile. Time proportional to change scope |\n| No-op build | \u003C 5 seconds for small repos, \u003C 30 seconds for large repos. All compilation targets should report \"Skipping target — all outputs up-to-date\" |\n\n**Red flags:**\n- No-op build > 30 seconds → incremental build is broken (see `incremental-build` skill)\n- Warm build recompiles everything → project dependency chain forces full rebuild\n- Cold build has long restore → NuGet cache issues\n\n### Recording Baselines\n\nRecord baselines in a structured way before and after optimization:\n\n```\n| Scenario | Before | After | Improvement |\n|-------------|---------|---------|-------------|\n| Cold build | 2m 15s | | |\n| Warm build | 1m 40s | | |\n| No-op build | 45s | | |\n```\n\n---\n\n## Step 2: MSBuild Server (Persistent Build Process)\n\nThe MSBuild server keeps the build process alive between invocations, avoiding JIT compilation and assembly loading overhead on every build.\n\n### Enabling MSBuild Server\n\n```bash\n# Enabled by default in .NET 8+ but can be forced\ndotnet build \u002Fp:UseSharedCompilation=true\n```\n\nThe MSBuild server is started automatically and reused across builds. The compiler server (VBCSCompiler \u002F `dotnet build-server`) is separate but complementary.\n\n### Managing the Build Server\n\n```bash\n# Check if the server is running\ndotnet build-server status\n\n# Shut down all build servers (useful when debugging)\ndotnet build-server shutdown\n```\n\n### When to Restart the Build Server\n\nRestart after:\n- Updating the .NET SDK\n- Changing MSBuild tooling (custom tasks, props, targets)\n- Debugging build infrastructure issues\n- Seeing stale behavior in repeated builds\n\n```bash\ndotnet build-server shutdown\ndotnet build\n```\n\n---\n\n## Step 3: Artifacts Output Layout\n\nThe `UseArtifactsOutput` feature (introduced in .NET 8) changes the output directory structure to avoid bin\u002Fobj clash issues and enable better caching.\n\n### Enabling Artifacts Output\n\n```xml\n\u003C!-- Directory.Build.props -->\n\u003CPropertyGroup>\n \u003CUseArtifactsOutput>true\u003C\u002FUseArtifactsOutput>\n\u003C\u002FPropertyGroup>\n```\n\n### Before vs After\n\n```\n# Traditional layout (before)\nsrc\u002F\n MyLib\u002F\n bin\u002FDebug\u002Fnet8.0\u002FMyLib.dll\n obj\u002FDebug\u002Fnet8.0\u002F...\n MyApp\u002F\n bin\u002FDebug\u002Fnet8.0\u002FMyApp.dll\n\n# Artifacts layout (after)\nartifacts\u002F\n bin\u002FMyLib\u002Fdebug\u002FMyLib.dll\n bin\u002FMyApp\u002Fdebug\u002FMyApp.dll\n obj\u002FMyLib\u002Fdebug\u002F...\n obj\u002FMyApp\u002Fdebug\u002F...\n```\n\n### Benefits\n\n- **No bin\u002Fobj clash**: Each project+configuration gets a unique path automatically\n- **Easier to cache**: Single `artifacts\u002F` directory to cache\u002Frestore in CI\n- **Cleaner .gitignore**: Just ignore `artifacts\u002F`\n- **Multi-targeting safe**: Each TFM gets its own subdirectory\n\n### Customizing\n\n```xml\n\u003C!-- Change the artifacts root -->\n\u003CPropertyGroup>\n \u003CArtifactsPath>$(MSBuildThisFileDirectory)output\u003C\u002FArtifactsPath>\n\u003C\u002FPropertyGroup>\n```\n\n---\n\n## Step 4: Deterministic Builds\n\nDeterministic builds produce byte-for-byte identical output given the same inputs. This is essential for build caching and reproducibility.\n\n### Enabling Deterministic Builds\n\n```xml\n\u003C!-- Directory.Build.props -->\n\u003CPropertyGroup>\n \u003C!-- Enabled by default in .NET SDK projects since SDK 2.0+ -->\n \u003CDeterministic>true\u003C\u002FDeterministic>\n\n \u003C!-- For full reproducibility, also set: -->\n \u003CContinuousIntegrationBuild Condition=\"'$(CI)' == 'true'\">true\u003C\u002FContinuousIntegrationBuild>\n\u003C\u002FPropertyGroup>\n```\n\n### What Deterministic Affects\n\n- Removes timestamps from PE headers\n- Uses consistent file paths in PDBs\n- Produces identical output for identical input\n\n### Why It Matters for Performance\n\n- **Build caching**: If outputs are deterministic, you can cache and reuse them across builds and machines\n- **CI optimization**: Skip rebuilding unchanged projects by comparing inputs\n- **Distributed builds**: Safe to cache compilation results in shared storage\n\n---\n\n## Step 5: Dependency Graph Trimming\n\nReducing unnecessary project references shortens the critical path and reduces what gets built.\n\n### Audit the Dependency Graph\n\n```bash\n# Visualize the dependency graph\ndotnet build \u002Fbl:graph.binlog\n\n# In the binlog, check project references and build times\n# Look for projects that are referenced but could be trimmed\n```\n\n### Techniques\n\n#### Remove Redundant Transitive References\n\n```xml\n\u003C!-- BAD: Utils is already referenced transitively via Core -->\n\u003CItemGroup>\n \u003CProjectReference Include=\"..\\Core\\Core.csproj\" \u002F>\n \u003CProjectReference Include=\"..\\Utils\\Utils.csproj\" \u002F>\n\u003C\u002FItemGroup>\n\n\u003C!-- GOOD: Let transitive references flow automatically -->\n\u003CItemGroup>\n \u003CProjectReference Include=\"..\\Core\\Core.csproj\" \u002F>\n\u003C\u002FItemGroup>\n```\n\n#### Build-Order-Only References\n\nWhen you need a project to build before yours but don't need its assembly output:\n\n```xml\n\u003C!-- Only ensures build order, doesn't reference the output assembly -->\n\u003CProjectReference Include=\"..\\CodeGen\\CodeGen.csproj\"\n ReferenceOutputAssembly=\"false\" \u002F>\n```\n\n#### Prevent Transitive Flow\n\nWhen a dependency is an internal implementation detail that shouldn't flow to consumers:\n\n```xml\n\u003C!-- Don't expose this dependency transitively -->\n\u003CProjectReference Include=\"..\\InternalHelpers\\InternalHelpers.csproj\"\n PrivateAssets=\"all\" \u002F>\n```\n\n#### Disable Transitive Project References\n\nFor explicit-only dependency management (extreme measure for very large repos):\n\n```xml\n\u003CPropertyGroup>\n \u003CDisableTransitiveProjectReferences>true\u003C\u002FDisableTransitiveProjectReferences>\n\u003C\u002FPropertyGroup>\n```\n\n**Caution**: This requires all dependencies to be listed explicitly. Only use in large repos where transitive closure is causing excessive rebuilds.\n\n---\n\n## Step 6: Static Graph Builds (`\u002Fgraph`)\n\nStatic graph mode evaluates the entire project graph before building, enabling better scheduling and isolation.\n\n### Enabling Graph Build\n\n```bash\n# Single invocation\ndotnet build \u002Fgraph\n\n# With binary log for analysis\ndotnet build \u002Fgraph \u002Fbl:graph-build.binlog\n```\n\n### Benefits\n\n- **Better parallelism**: MSBuild knows the full graph upfront and can schedule optimally\n- **Build isolation**: Each project builds in isolation (no cross-project state leakage)\n- **Caching potential**: With isolation, individual project results can be cached\n\n### When to Use\n\n| Scenario | Recommendation |\n|----------|---------------|\n| Large multi-project solution (20+ projects) | ✅ Try `\u002Fgraph` — may see significant parallelism gains |\n| Small solution (\u003C 5 projects) | ❌ Overhead of graph evaluation outweighs benefits |\n| CI builds | ✅ Graph builds are more predictable and parallelizable |\n| Local development | ⚠️ Test both — may or may not help depending on project structure |\n\n### Troubleshooting Graph Build\n\nGraph build requires that all `ProjectReference` items are statically determinable (no dynamic references computed in targets). If graph build fails:\n\n```\nerror MSB4260: Project reference \"...\" could not be resolved with static graph.\n```\n\n**Fix**: Ensure all `ProjectReference` items are declared in `\u003CItemGroup>` outside of targets (not dynamically computed inside `\u003CTarget>` blocks).\n\n---\n\n## Step 7: Parallel Build Tuning\n\n### MaxCpuCount\n\n```bash\n# Use all available cores (default in dotnet build)\ndotnet build -m\n\n# Specify explicit core count (useful for CI with shared agents)\ndotnet build -m:4\n\n# MSBuild.exe syntax\nmsbuild \u002Fm:8 MySolution.sln\n```\n\n### Identifying Parallelism Bottlenecks\n\nIn a binlog, look for:\n- **Long sequential chains**: Projects that must build one after another due to dependencies\n- **Uneven load**: Some build nodes idle while others are overloaded\n- **Single-project bottleneck**: One large project on the critical path that blocks everything\n\nUse `grep 'Target Performance Summary' -A 30 full.log` in binlog analysis to see build node utilization.\n\n### Reducing the Critical Path\n\nThe critical path is the longest chain of dependent projects. To shorten it:\n\n1. **Break large projects into smaller ones** that can build in parallel\n2. **Remove unnecessary ProjectReferences** (see Step 5)\n3. **Use `ReferenceOutputAssembly=\"false\"`** for build-order-only dependencies\n4. **Move shared code to a base library** that builds first, then parallelize consumers\n\n---\n\n## Step 8: Additional Quick Wins\n\n### Separate Restore from Build\n\n```bash\n# In CI, restore once then build without restore\ndotnet restore\ndotnet build --no-restore -m\ndotnet test --no-build\n```\n\n### Skip Unnecessary Targets\n\n```bash\n# Skip building documentation\ndotnet build \u002Fp:GenerateDocumentationFile=false\n\n# Skip analyzers during development (not for CI!)\ndotnet build \u002Fp:RunAnalyzers=false\n```\n\n### Use Project-Level Filtering\n\n```bash\n# Build only the project you're working on (and its dependencies)\ndotnet build src\u002FMyApp\u002FMyApp.csproj\n\n# Don't build the entire solution if you only need one project\n```\n\n### Binary Log for All Investigations\n\nAlways start with a binlog:\n```bash\ndotnet build \u002Fbl:perf.binlog -m\n```\n\nThen use the `build-perf-diagnostics` skill and binlog tools for systematic bottleneck identification.\n\n---\n\n## Optimization Decision Tree\n\n```\nIs your no-op build slow (> 10s per project)?\n├── YES → See `incremental-build` skill (fix Inputs\u002FOutputs)\n└── NO\n Is your cold build slow?\n ├── YES\n │ Is restore slow?\n │ ├── YES → Optimize NuGet restore (use lock files, configure local cache)\n │ └── NO\n │ Is compilation slow?\n │ ├── YES\n │ │ Are analyzers\u002Fgenerators slow?\n │ │ ├── YES → See `build-perf-diagnostics` skill\n │ │ └── NO → Check parallelism, graph build, critical path (this skill + `build-parallelism`)\n │ └── NO → Check custom targets (binlog analysis via `build-perf-diagnostics`)\n └── NO\n Is your warm build slow?\n ├── YES → Projects rebuilding unnecessarily → check `incremental-build` skill\n └── NO → Build is healthy! Consider graph build or UseArtifactsOutput for further gains\n```\n",{"data":38,"body":39},{"name":4,"description":6,"license":28},{"type":40,"children":41},"root",[42,51,58,72,80,130,134,140,145,152,157,313,319,324,397,403,408,472,478,545,553,578,584,589,599,602,608,613,619,655,668,674,737,743,748,771,805,808,814,827,833,874,880,889,895,951,957,994,997,1003,1008,1014,1081,1087,1105,1111,1144,1147,1153,1158,1164,1218,1224,1231,1315,1321,1326,1357,1363,1368,1399,1405,1410,1439,1449,1452,1466,1471,1477,1544,1549,1582,1588,1668,1674,1687,1696,1729,1732,1738,1744,1838,1844,1849,1882,1895,1901,1906,1955,1958,1964,1970,2034,2040,2111,2117,2163,2169,2174,2201,2213,2216,2222,2231],{"type":43,"tag":44,"props":45,"children":47},"element","h1",{"id":46},"build-performance-baseline-optimization",[48],{"type":49,"value":50},"text","Build Performance Baseline & Optimization",{"type":43,"tag":52,"props":53,"children":55},"h2",{"id":54},"overview",[56],{"type":49,"value":57},"Overview",{"type":43,"tag":59,"props":60,"children":61},"p",{},[62,64,70],{"type":49,"value":63},"Before optimizing a build, you need a ",{"type":43,"tag":65,"props":66,"children":67},"strong",{},[68],{"type":49,"value":69},"baseline",{"type":49,"value":71},".
