 I'll run some more tests with different filesystems to see if this is
 related to the use of EXT3 specifically.

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.
