Hi Malcolm, Hi Joe,
The last time that I did some micro-benchmarking of LVS I found Julian's
lvs-test to be of use. http://www.ssi.bg/~ja/
More generally, when doing network benchmarking I find netperf to be very
useful. Though most of my work using netperf has been for single streams,
which is not particularly exciting in the context of LVS.
The in-kernel packet generator is also interesting, though I don't recall
ever getting particularly useful benchmarks out of using it.
