+If this option is set to a value greater than zero, the C<rrdtool>-plugin will
+write values every I<Seconds> seconds to the RRD-files. Writing multiple values
+at once reduces IO-operations and thus lessens the load produced by updating
+the files. The tradeoff is that the graphs kind of "drag behind" and that more
+memory is used.
