描述

Atom had an interesting strategy for improving startup performance in their blog post here: http://blog.atom.io/2017/04/18/improving-startup-time.html

They are leveraging V8 snapshots to output a JS heap. This saves all the parsing and processing of JS, which is non-trivial as the bundle.js for this project gets larger.

There are some restrictions (V8 snapshots run in a bare V8 context), so it's important to have solid testing to ensure we aren't breaking anything in these cases.

研究方向
Investigate the V8 snapshot approach used by Atom as described in the linked blog post. Analyze Oni's current startup sequence to identify which modules are loaded early. Determine the feasibility of pre compiling a heap snapshot of the JavaScript bundle. Consider the testing strategy to ensure no regressions in functionality.
