Database Tuning
You have the abbility to define which columns may be fetched from the Database for Item calls.
A configuration holds all columns for the several Itemtypes.
Look at the File /consumer/cid{CID}/config/config.select.inc.php for further information. Tuning these select columns may result in better performance.
Tip: If the system might not be running after modifing the configuration, use the backup file from /consumer/cid{CID}/config/config.select.inc.php.
