Running a filesystem on top of iSCSI results in better performance than NFS, especially if the NFS client conforms to the NFS standard (=synchronous writes). By searching the web search for the keywords NFS, iSCSI and performance I found the following (6 years old) document: http://www.technomagesinc.com/papers/ip_paper.html. A quote from the conclusion: Our results, generated by running some of industry standard benchmarks, show that iSCSI significantly outperforms NFS for situations when performing streaming, database like accesses and small file transactions.
