You cannot provide consistency for more than one active connection without locking, because file system writes are not atomic. ie. during COMMIT there is a window where if another process was allowed to read the DB it would see garbage and report "corrupt database" rather than consistent results. I'm not very familiar with WAL mode but I think the critical locking stage there is checkpointing rather than COMMIT. If you're not happy with the INSERT speed, batch your writes. -Rowan _______________________________________________ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
