I first tested the same client to the same server using Linux (same configuration as the server) and netperf, then NFS, then cifs mount. Netperf (TCP_SENDFILE test) gives more than 9500 Mb/s both direction, so the network hardware works OK. NFS gives the following results both in UDP and TCP modes: Sustained throughput: 490 to 520 MB/s write, 620 to 650 MB/s read. The linux CIFS client running on the same machine writes at a puny 180 MB/s and read at...
