+# Case Study - Nx graph time
+
+## Measured graphs
+
+Use native Node.js CPU profiling to analyze where time is spent when calculating Nx graphs.
+
+### Project Graph
+
+Measure the project graph creation:
+
+```bash
+# Prerequisite (once): install local deps so ./node_modules/.bin/nx exists
+NX_DAEMON=false NX_CACHE=false \
+npx -y @push-based/cpu-prof \
+--cpu-prof-dir ./profiles/nx-show-projects \
+node ./node_modules/nx/bin/nx.js show projects --json
+```
+
+### Task Graph
+
+Measure the task graph creation:
+
+```bash
+# Prerequisite (once): install local deps so ./node_modules/.bin/nx exists
+NX_DAEMON=false NX_CACHE=false \
+npx -y @push-based/cpu-prof \
+--cpu-prof-dir ./profiles/nx-show-project \
+node ./node_modules/nx/bin/nx.js show project <project-name> --json
+```
