What you actually measured is the latency in idle state ;-) Open a console and run while : ; do time sh -c "dd if=/dev/zero of=bigfile bs=8M count=256 ; sync; rm bigfile"; done Then, open another one and run fsync-tester. The numbers that count to compare different elevators on your system is the output fsync-tester generates while your machine is generating the "bigfile". -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
