Doing an export of a number of users causes high CPU and I/O usage. I can mitigate the effects of the CPU usage using Resource Manager and setting the export session to a low priority group, but how can I limit the disk I/O? I am not running the operation in parallel and have already read Oracle's Datapump Performance documentation. Is there anything else I can do?

Ionice can limit disk usage

Take a look at the ionice utility for linux, as it seems to suit your needs quite well.

Great answer, unfortunately I need to do this on windows, but since I didn't specify that I'll accept your answer and tag this for linux and then ask again with a windows tag. –  Leigh Riffel Jan 7 '11 at 15:25
