This is exactly the type of test I run(TCP_STREAM tests at very high
sustained speeds). And I saw very good performance improvement when
increasing the TxDescriptors to at least 1024.
I run a network benchmark in this case the data I gathered was on 4 way,
1.45 Ghz systems, running the benchmark on only one adapter per machine,
point-to-point.
