I do love sqlite, it really is awesome, but you had better need what it provides, since you are taking a 50x performance hit versus simply dumping an object tree to a binary file.
If anyone is interested, I could try and dig up my notes from switching from sqlite to NSArchive.
The overall speedup when loading was about 50x, when using NSArchive versus sqlite3. Neither implementation was or has been optimized, though I did try to write the sqlite3 code as efficiently as possible, since it was clearly a source of slowness from day 1.
