Obviously the } write performance is just what you want, but I seem to remember } hearing about problems with expiring because free space doesn't appear } immediately. It works great! The space problem isn't an issue for a news spool because the free space created by expire appears well before it is needed for new articles. The space problem is only deadly when a partition is nearly full, and files are rapidly deleted and created. It might take a minute or so for the free space from the deleted files to become available and if the amount of space required for the new files created during that time is more than the amount of free space that you start with then you'll run out of room before the "new" free space becomes visible.
