Much of the system CPU usage does appear to be due to the use of EXT3;
the load with EXT2 is around half that with EXT3.

See graph of results: http://www.ubergeek.org.uk/cpu_usage.png

For Windows, the graph shows total CPU usage as reported by the OS.
For Linux, the combined User+System figure was used.
