Read Performance

NAS read performance more truly represents what the actual device is capable of, since caching generally doesn't have any effect. Figure 11 shows excellent read performance with a 100Mbps Ethernet connection, running between 8,000 and 10,000 kBytes/sec for a wide range of record and file sizes. Note that the vertical scale in both figures is reduced by more than an order of magnitude from the write plots.

Figures 12 shows that the NV can make good use of its gigabit Ethernet option. Note the slightly greater than 4X change in the Y axis scale and peak read speeds above 35,000 kBytes/sec.

Since the NV doesn't implement jumbo frames for when being read from, I'm not going to bother showing plots for the 4K and 9k Jumbo frame tests.
