I have tested on N900 (MeeGo 1.2 Community Edition on microSDHC class 4
card), it takes 0.1 second to load and parse the mobile-provider-info
database (154KB).
Is this a reasonable time or should we go with pre-parsing?
My rule of thumb is less than 300 ms is not really noticeable to the
user and anything up to 1 second is OK. So in this case I'd say we
should be fine parsing on demand.
If we ever encounter performance problems we can revisit this decision.
