The big one is still running, so we'll see - but I do think already there is something very different. Simon might be on to something with the cache. The journal mode should also make a difference, but not that big I think. Once this run finishes, I will try the 10-Mil one with different journal modes. I have never noticed a large time taken for dropping tables though, but then I do not often drop very large tables. > If useful, I could share the program I am using. As long as the version is known and the modes used, the rest of the software differences should be small - it's usually down to hardware.
