I need to insert approximately one million rows of data (spread over 4 tables) - each row has one or two numeric fields, and two or three text fields (normally quite short). Single-column indexes on all the fields.
After doing some tests on the emulator with a small test set, I extrapolated (assuming the last row will be inserted with a similar speed to the first row) my results to figure out that this would take about 15 hours (I have a Core 2 Duo running Vista). However, then I tried running the small test set on my Hero and I was surprised to see it run more than four times faster. I would guess it would take about 3 hours on the Hero. Alternatively, I could make the pre-populated database available as a download on the first run but this is likely to be a 120MB download. I have a few questions I'm hoping someone can help me with: 1. SQLite performance on the actual device being 4-5 times faster compared to the emulator - is this normal/expected? 2. Do the figures above generally sound fast/slow/normal (sorry this is so vague)? 3. From a user perspective - would it be best to provide a 120MB download or a 3 hour "first-time initialisation" step (plus 6MB download)? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
