Minor "heavy load" Tweak


Finding (more often than none!) that Zimbra run's at a heavy load - with few or many users on a server. One quick tweak is to shut off the logger & swatch. You do loose the nice Graphing charts in the Admin panel (:7071) ... but you do gain back some performance and reduce that heavy load fluctuation (I've personally seen upwards to load of 250 with only 100 users!)

To shut off logger, as user "zimbra":

 zmloggerctl stop ;
 zmswatchctl stop ;
