React Native Android JS Performance Measurements

A simple react native app with some performance benchmarks.

Past measurements are saved into results

The table blow is generated by calling npm run generateReadmeTable

How to run

1. Compile the jsc locally (from root project, so that the compiled result will be at /dist)
2. Connect a physical device
3. npm i from within /measure
4. npm run start. This will compile a release version of the profiler app with the jsc from /dist and start measurements automatically.
5. After the tests finish, the timings will be printed. The results.json needs to be updated manually, then the table below can be generated.
6. You can run the tests manually: inside the app select one of the tests for it to execute. To run a different test close the app and remove it from recent apps to release all memory.

Measurements

• All timings in milliseconds (lower is better)
• Size in MB (arm32/arm64)
• Render is measured with 1000 elements, flat or deep. The timing is taken after a full render roundtrip (after onLayout)
• Synthetic tests were modified to be able to run on RN environment, based on the following:
  • jetstream
  • octane2
  • sixspeed
  • sunspider
• All measurements run on (a very clean) Pixel XL, release mode
