INVESTIGATE: improving startup performance

[amilajack]

Things to investigate

• [x] Dynamically import only parts of falcon-core that are necessary
• [x] async/lazyload routes with react-router
• [x] Service worker to reduce network startup
• [ ] prepack (waiting for this project to mature)
• [ ] Native compile cache
• [ ] electron-link (v8 snapshots)

NOTE: Requiring falcon-core reduces startup perf by 1 whole second

[amilajack]

comparing to erb perf (in production). should use it as a baseline. Half a second startup

falcon in production: 2sec startup, after removing unnecessary native dependencies

falcon in production: 1.4sec startup, after async routes
