No, I didn't see a longer run time of diotest6 itself on RHEL6/7.

But I enabled dio30, which runs "diotest6 -b 65536 -n 100 -i 1000 -o
1024000" and takes longer time (from 10 minutes to 1 hour, depends on
your host configuration), see commit 71f253f7d74d ("runtest/dio: enable
dio29/30"). Is this your case?

Thanks,
Eryu
