If there is any price break on getting a single port, I strongly
I'm only getting ~340MB/s reads and ~500MB/s writes through my samba
server with a dual card (and those are maximums for large transfers in
to/from a Win7 workstation. I'd been hoping for at least 50-60% utilization
vs. the 14-20% MAX throughput (note, these figures are through samba -- file
xfer using ssh is WAY slower).
For comparison. with the same test setup I got 125MB/s writes & 119MB/s
over a 1Gb connection (same machines).
Needless to say, I was very unimpressed by the drop in efficiency.
Thinking about it .. a dual 1Gb card maxes out an 8-bit pci-e slot, so I
know if you are going to see alot of benefit with a faster card.
