Hi Christiaan, If you haven't found it already, I highly recommend going through the information at these three urls: http://www.solarisinternals.com/wiki/index.php/ZFS_Configuration_Guide http://www.solarisinternals.com/wiki/index.php/ZFS_Best_Practices_Guide http://www.solarisinternals.com/wiki/index.php/ZFS_Evil_Tuning_Guide I'll defer to Richard Elling and Roch Bourbonnais for specific suggestions based on your email - as far as I'm concerned they're the experts when it comes to ZFS tuning and database performance.
