Figure 6.
Figure 6 shows the results of the sequential read tests. The aggregate throughput achieved when a
number of clients are simultaneously reading files is plotted on the graph. The figures show the peak
read throughput for the baseline is ~2,500 MiB/s. With the DFC configuration, reads are 13% to 60%
