Issues
Trunk Firefox takes ~15s to show the main window on the N800. With a simpler chrome it reduces to about 8s. The Maemo browser on the same hardware takes ~3s, and Safari (iPod Touch) takes less than a second.
Goals
Initial goal: Reduce startup time as perceived by the user to less than 3s.
Task list
Here are some potential optimizations:
- Improve fastload performance
- Filed bug 412796 [1]
- Optimize mobile chrome
- UI design
- XUL Optimizations
- Function re-ordering
- Streamline memory access by placing all code & data needed for start-up in contiguous sections at the start of the binary.
- Optimize memory allocation
- Significant time during startup is in memory allocations. Need link to ongoing work.
- Optimize startup hotspots
- Bug 406810 [2]
- Preload Mozilla libraries
- Preload all libraries during startup; launching Firefox only loads the XUL application.
- Preload Mozilla application
- Launch Mozilla during device startup and keep in background (no visible window). Launching Firefox will only open a new window.
- Identify & disable unnecessary work during startup (for mobile)
- Bug 421561 [3]
