+commit=nrsec   (*)     Ext3 can be told to sync all its data and metadata
+                       every 'nrsec' seconds. The default value is 5 seconds.
+                       This means that if you lose your power, you will lose,
+                       as much, the latest 5 seconds of work (your filesystem
+                       will not be damaged though, thanks to journaling). This
+                       default value (or any low value) will hurt performance,
+                       but it's good for data-safety. Setting it to 0 will
+                       have the same effect than leaving the default 5 sec.
