Any information would be helpful, although I am particularly interested in results that strictly exercise only network I/O, that is, in memory to memory transfers, such as over iperf or netpipe, and in both full/half duplex configuration.
I had overlooked this set of results: http://www4.tomshardware.com/motherboard/20040430/gigabit_ethernet-09.html
These results suggest that CSA works as advertised (it breaks the PCI 32/33 barrier). However, these tests were run in WinXP, not Linux. The netperf baseline is considerably lower than my memory-to-memory measurements on similar hardware, and the PCI-X system performs worse than I expected. Nevertheless, CSA does work as advertised in breaking past the PCI bottleneck.
I'm contacting the authors to see if they have any results of that article. I'd still like to learn about Linux user experiences with this hardware.
