Notes	This project will start by exploring viability of such a benchmark. If the benchmark turns out to be infeasible, we will document the results and move on to another project. The benchmark approach was infeasible. Alternative tests will be considered.

Product impact	[DESKTOP] [MOBILE]
Goal	Goal: Reduce Add-on Manager impact on start-up time¹ and runtime pauses² by removing SQLITE database from XPI Provider and Add-on Repository and replacing with JSON³. ¹Start-up time reduction by reducing the amount of I/O required before first paint. ²Runtime pause reduction by reducing I/O required during add-on up-to-date checks and updates, and making sure as much as possible is off main thread. ³New implementation will do no blocking I/O except minimal loading of required data during start-up.
Duration	6 weeks (approx week of May 27, 2013)

Duration	Mid August for reaching the initial goal in Nightly. Probably another month or two (with lower bandwidth) for follow-ups.
