The performance of a network file system, i.e. how fast your computer can read / write data to a network drive, depends on factors specific to the system running the test. So put the results in perspective, I compared the iozone results against a Linksys NSLU2, Buffalo Technology Kuro Box, Simple Tech SimpleShare, Synology Diskstation and Maxtor Simple Share.
The plots in Figures 13 and 14 show read and write speeds respectively for a fixed file size of 128 MBytes and record sizes from 64 to 16384 kBytes. Experience has shown that a file size of 128 MBytes usually shows performance free of caching effects and therefore more indicative of what the product itself is capable of. Since the same test computer and network connection was used for all tests shown, the results are about as apples-to-apples as you're gonna get.
The plots show both the Net-Stor and Simple NAS at the bottom of the pack for both read and write, with the Tritton Simple NAS taking the prize for poorest performance seen to date!
