We finally have some data.

This is from end-2005 running 6.0-release. The output was generated, while the
system was very unresponsive, the user has since stopped using FreeBSD and is
thus not able to provide us with newer data:

Running dd causes the system to be unresponsive even though the CPU load is
not very high:
