Since each insert statement will now require an explicit disk flush, it will be very slow. Is there *really* no way to group multiple writes together? As you've likely read elsewhere, doing so can provide orders of magnitude performance improvements-- well worth the effort to reorganize your architecture a bit. > 1) are these expected performance on windows? > 2) if not, what can be done to improve it? If you really must run the statements individually, you have a few (less than perfect) alternatives: - Turn off synchronous writes ("pragma synchronous = OFF"). Though this will dramatically improve your insert performance, you will be running without any safety net: If the application crashes or exits during a write, your database may become (permanently) corrupted. - The compiler optimizations (above) will likely help somewhat, though not terribly much. - A faster (higher RPM) hard drive will help somewhat. ~Eric _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
