Interesting machine the microserver...And what about the CIFS tranfers?
With a Windows 7 SP1 PC (Intel i7-870/8GB RAM, Realtek GigE) and CIFS, when reading an 8GB file from the Microserver-based FreeNAS 8.0.2-BETA2 to an Intel X-25M SSD in the PC, the speed averaged 60MB/s-63MB/s, and when writing the same 8GB file from the SSD back to the FreeNAS the speed averaged 65MB/s-70MB/s.
Note that I've installed a cheap £20 Intel Pro-1000 CT NIC and disabled the built-in Broadcom NIC as the latter gave me problems when testing with iperf - the bge driver would hang and reset the NIC, apparently a long standing issue with this driver and BSD so the easiest solution was to go Intel.
Both PC and FreeNAS are connected to a Netgear GigE switch, and Jumbo Frames are not enabled. I could probably get slightly better results if I dumped the Realtek in the PC, as this is now most likely the last remaining "bottleneck" although to be honest I'm happy as it is with the performance.
I did notice a significant performance improvement after I recreated the volume in 8.0.1-BETA2 with forced 4K sectors - it had previously been created in 8.0-RELEASE without 4K sector support (dd performance was about 100MB/s read, 80MB/s write).
