Hi, Mark I have some doubts on selecting workload for storage performance testing. It seems the configuration in StorPerf[1] is quite different from the SSS PTS[2]
In StorPerf, it seems throughput, iops and latency are measured under the same set of workloads. However in SSS PTS, it selects different workload for measuring different metrics. For example, for measuring throughput, only large block sizes (128KiB and 1024KiB) at Sequential Read/Write (100/0, 0/100) is selected. But in latency measurements, only small block sizes (0.5 KiB, 4KiB and 8KiB) is used. Why is such difference, any special consideration?
