It sounds like the first case is using transactions and/or has "PRAGMA synchronous" turned off, while the second one is inserting records one at a time. The low CPU indicates a lot of thumb twiddling while waiting for physical I/O. I suppose the other possibility is that the first machine lies to SQLite about when the writes actually hit spinning disk, while the second version does not. -j -- Jay A.
