The practical guidelines are useful. Basically “first prove I/O is actually your bottleneck, then change the architecture to use async/batching, and only then reach for features like fixed buffers / zero-copy / passthrough / polling.”
I'm curious, how sensitive are the results to kernel version & deployment environments?
Some folks run LTS kernels and/or containers where io_uring may be restricted by default.
