Is moving the databases (IMAP metadata) to a separate ZFS filesystem likely to improve performance? I've heard that this is important, but I'm not clear why this is.
There is an obvious potential benefit in that you are then able to tune filesystem parameters to best fit the needs of the application which updates the data. For example, if the database uses a small block size, then you can set the filesystem blocksize to match. If the database uses memory mapped files, then using a filesystem blocksize which is closest to the MMU page size may improve performance.
