Can someone recommend a linux utility to reliably benchmark IOPS on local, NFS and iSCSI volumes?
I need something that can handle large data sets (definitely over 32G, ideally even larger) and 10G ethernet bandwidth.
I've tried Bonnie++ (measures bandwidth but not IOPS), iorate (can't seem to work with datasets larger than 4G, can't seem to saturate a 1G ethernet), and fio doesn't seem to provide reliable results (I'll run the same test twice with completely different results).
Thanks for your input.
