...se (see
below).
The systems are connected in 10GigE ethernet using Myricom Myri-10G
dual ports (only one port used) through a Fujitsu 10GigE switch.
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...
