Our last set of profiles include File Server and Web Server workloads. As mentioned before the last hour of preconditioning, the average IOPS, and average latency for each QD is graphed below.

It’s made up of block sizes from 512 to 64K, each making up a different percentage of the access pattern. The pattern is: 512 bytes=10%, 1k=5%, 2k=5%, 4k=60%, 8k=2%, 16k=4%, 32k=4%, 64k=10%.

During the File Server benchmark we can see very similar performance to that of our Email Server results, only now a bit better results. Under this mixed workload the Toshiba takes the lead from QD2-16, but at QD32 the Samsung prevails. Latency reaches just above 1.5ms and IOPS reach nearly 21K at QD32.

The Web Server profile is similar to the File Server profile, but has some additional 128K and 512K accesses thrown in for good measure. Additionally, the profile is 100% reads.

For the Web Server benchmark looks to be bested once again across the board, but by a close margin! Overall, it reached nearly 31K IOPS and latency reached just over 1ms at QD32.
