Try the grep package from FC3 updates -- I think it should work okay on FC2 as well. It'll be because you're running in a non-C locale, and so grep is obliged to perform more work to get locale sorting order correct. The efficiency for UTF-8 processing has been improved in the FC3 updates package. Tim. */
