Figure: Read performance of the JNFS system vs. NFS on several different file sizes.

Performance in our simulations was reasonable for a Java application, but not nearly as good as NFS. On average, JNFS file transfers take about 8 times as long as analogous NFS transfers on a Sun SparcStation 10 running Solaris 2.5. We present a comparison of JNFS and NFS read speeds on various different file sizes in Figure 2. There are several factors that lead to worse performance in our simulation:
