No question. Sequentially reading and writing works fine. The cost for NFS is in metadata operations, including opening files because an open traverses the pathname component-by-component. I could get a noticeable improvement by patching pkgsrc to use relative pathnames instead of absolute ones. A local filesystem (and that it includes a local filesystem on an iSCSI disk) doesn't have that overhead.
