690898 - Use pre-built SQLite DBs when creating a new profile

Status: RESOLVED DUPLICATE of bug 699615

(Firefox for Android Graveyard :: General, defect)

Description

[Mark Finkle (:mfinkle) (use needinfo?)]

When creating a new profile in Firefox Mobile, it takes a long time. Much of this is time spent building SQLite databases using SQL commands.

It might be interesting to see if we can make the process faster by copying pre-built DBs into the new profile.

Early benchmarking seems to hint that much of the time spent in SQLite is actually spent committing files to storage. By using fs-based transactions instead of sqlite-based transactions, we can probably remove most of this overhead, without having to grow the binary.

Barring any accident, I'm starting work on this today.
