Happy that's using the fix I have sent for coordinated omission

Low latency won't matter if not measured right

And thanks to for making the performance community aware of Coordinated Omission. Hopefully, more Load Testing tools will pick up this solution for addressing it.
Something I have found about coordinated omission is; a) there are case ls for low throughput that it makes remarkably little difference, b) if the producer doesn't back off, not just the percentiles increase but the worst case is higher, up to 10x
Can be a lot more than 10x 
. E.g. if you take in requests at 1K per second for 100 seconds into a system that serves requests one at a time and takes 10 msec to serve each, you’ll see a max response time of 90,000 msec. That’s 900x, and it’s real.
