Are you already doing multiple updates per update command?

rrdtool update x.rrd <timestamp>:<values>
rrdtool update x.rrd <timestamp>:<values>
rrdtool update x.rrd <timestamp>:<values>
rrdtool update y.rrd <timestamp>:<values>
rrdtool update y.rrd <timestamp>:<values>
rrdtool update y.rrd <timestamp>:<values>
rrdtool update z.rrd <timestamp>:<values>
rrdtool update z.rrd <timestamp>:<values>
rrdtool update z.rrd <timestamp>:<values>

could be

rrdtool update x.rrd <timestamp>:<values> <timestamp>:<values> <timestamp>:<values>
rrdtool update y.rrd <timestamp>:<values> <timestamp>:<values> <timestamp>:<values>
rrdtool update z.rrd <timestamp>:<values> <timestamp>:<values> <timestamp>:<values>

or even

(
echo update x.rrd <timestamp>:<values> <timestamp>:<values> <timestamp>:<values>
echo update y.rrd <timestamp>:<values> <timestamp>:<values> <timestamp>:<values>
echo update z.rrd <timestamp>:<values> <timestamp>:<values> <timestamp>:<values>
) | rrdtool -

If you are already doing this, then you must have lots of data to process...
