Hi,

Can any one share some performance test data/results with multiple physical paths?

- What is the expectation on multiple physical path without link aggregation?
  e.g. direct cable connection host1.eth0 to host2.eth0 and host1.eth1 to host2.eth1,
          eth0s were place in one subnet and eth1s are placed in another subnet.

- What is the expectation on multiple physical paths under link aggregation?
  = If the maximum bandwidth between two nodes is all that I am caring, is round-robin the best configuration?
  = If link aggregation was tested, is there any preferred swtich (maker model)?

- For either case above:
  = any tips for performance tuning?
  = What is the expected performance at 0ms, 5ms, 10ms, 100ms, 200ms? (for simplicity, assume 2 GigE links).

Thanks,
Ying
