angular-cn/packages/core/test/render3/perf/README.md

Build

yarn bazel build //packages/core/test/render3/perf:{name}.min_debug.es2015.js --define=compile=aot

Run

node dist/bin/packages/core/test/render3/perf/{name}.min_debug.es2015.js

Profile

node --no-turbo-inlining --inspect-brk dist/bin/packages/core/test/render3/perf/{name}.min_debug.es2015.js

then connect with a debugger (the --inspect-brk option will make sure that benchmark execution doesn't start until a debugger is connected and the code execution is manually resumed).

The actual benchmark code has calls that will start (console.profile) and stop (console.profileEnd) a profiling session.

Notes

In all the above commands {name} should be replaced with the actual benchmark (folder) name, ex.:

• build: yarn bazel build //packages/core/test/render3/perf:noop_change_detection.min_debug.es2015.js --define=compile=aot
• run: time node dist/bin/packages/core/test/render3/perf/noop_change_detection.min_debug.es2015.js
