slow egrep

Hi,
at "http://directory.fsf.org/grep.html"; you say about "egrep", that "the
result is usually many times faster that UNIX 'grep' or 'egrep.'"

I discovered, that in my case, gnu-egrep (2.5.1) is over thousand times
slower then for example HP-UX-egrep.

Please make an "egrep -v -f xf xd" together with following 2 files appended
at the end of the mail and you can reproduce my case.


Is it easy to fix this problem?

Thanks.


Best regards,
Tobias
