High kafka latency on simple benchmark

[Виталий Ромашкин]

Hi Devs,
 
Currently, I am bench-marking different transports.
The first one is Kafka.
I created a repo in my GitHub —  https://github.com/rvit34/transport-benchmark
The result for Kafka is not so good. For RPS 25K and higher latency is about 
1second and higher.
Maybe I'm doing something completely wrong but If I change transport from Kafka 
to Aeron my max latency is always under 100ms for any workload (100K RPS and 
higher).
So, might somebody check it out?
 
 
Best Regards, Vitaly.
