and > The I/O is actually done by RRD4J, [...] a Java version of 'rrdtool' If it behaves like rrdtool, it will limit the size of the file, by consolidating older data. After every n samples, older data will be replaced by an aggregate, freeing space for new samples. To me that implies random I/O. You really need a tool like dtrace (or old fashioned truss) to see the sample rate and size.
