Thanks for starting this KIP Mickael. 1. Could we expand the scope of this KIP to include the linux kernel versions supported by Kafka? I am asking this because newer kernels have features such as io_uring and kernel based TLS, which could potentially be used to improve Kafka's performance. However, in the absence of documented kernel version requirements for each version of Kafka, it becomes difficult to understand whether a version could be modified to make use of these OS primitives or not.
2. In the process for onboarding new platforms, do you think it would make sense to perhaps have a one-time performance qualification test added there as well to establish a baseline? The performance test would determine the defaults for configuration. I am asking this because newer platforms may require different tuning/configuration to run Kafka and the default configuration should opt for providing an acceptable (baselined against other platforms) level of performance that works for the majority of use cases.
