Description

Teletype is taking a long time to activate for me at around ~190ms. Looks like deferred activation isn't possible, but would it be feasible to defer some requires until they're needed? For example, until you try to host or join a portal, are the majority of requires needed?

Steps to Reproduce

Enable teletype
Reload atom
Look at how long teletype took to activate

Expected behavior: Preferably <25ms

Actual behavior: ~190ms

Reproduces how often: 100%

研究方向: The issue suggests deferring requires until needed. Look at the main entry point (e.g., index.js or lib/teletype.js) to identify all require statements. Consider lazy loading modules that are only needed for hosting or joining portals. Profile the activation time using Atom's timecop feature to measure improvement. Check if any side effects occur from deferred loading.
