This white paper describes the performance difference among NFS, SMB, and iSCSI network storage protocols when running FIO workloads in a KVM environment. Abstract iSCSI, NFS, and SMB protocols provide access to storage resources via a TCP/IP network. While iSCSI provides block device access, NFS and SMB are file-level access protocols.

To facilitate his block layer work in the Linux kernel, Axboe created the flexible IO tester (fio) benchmarking and workload simulation tool. fio is able to simulate various types of I/O loads, such as synchronous, asynchronous, mmap, etc., as well as specifying the number of threads or processes, read vs. write mix, and various other parameters. fio was used to set the record in December 2012 for the highest number of I/Os-per-second (IOPS) in a single system.

But we want a nice consistent tool for the job. I had thought of rolling one, until I found Jens Axboe’s fio tool. With this, I can recreate the relevant workloads fairly easily. Of course, the purpose of this post is not to talk about fio. But instead to talk (a little) about a new project we took out to the test track.

When fio (using libaio as in your example) runs at about 100% of cpu time, it is spending all of its time between io_submit()s and io_getevent()s. Think of fio telling the kernel "submit these 64 requests", but by the time it finishes doing that, some of those requests are completed. Then it calls io_getevent() and collect those completed requests. Slow ZFS Performance with fio on a pure-ssd pool with optane 900p SLOG.
