I think I might need to understand the goal here a bit more.

I started down the path of adding seeding to the mc-hammer to allow it to do something closer to reproducible, but as it's a multi-threaded network client, I'm not sure how realistic it is to expect a given test to ever produce the same results twice.

That is, multi-threaded network clients that go as fast they can are inherently non-deterministic.

For reproducibility, it might be best to try to use some type of packet capture-based approach. I know there are some tools that do this kind of thing, but I don't know how well they work at load.

ok. We will revisit the tools we need and whether modifying mc_hammer or creating a new tool is the right approach
