Pretty much what NateB said* - but that might leave you at "what's wrong with that? that's how I could get it done"

There's WAY too much content, way too many names and stuff that feels subtly off. I'm 37, been on this site for 16 years. I'm assuming target audience here is enterprise Java developers, which isn't my home, so I'm sure I'm missing some stuff is idiomatic in that culture.

But the vast, vast amount of things that are completely unfamiliar tells me something else is going on and it's not good.

Like I bet this is f'ing cool, otherwise you wouldn't put in the effort to share it. But you're better off having something super brief** in a GitHub README than a pseudo-marketing site that's straining to fit a cool technical thing into the wrong template.

** what you wrote is great! "The payload is encoded using myra-codec FFM MemorySegment directly into a pre-registered buffer in io_uring SQE on the server. Similarly, on the client side CQE writes encoded payload directly into a client provided MemorySegment. The whole process saves a few SYSCALLs. Also, the above process is zero copy." -- then the site looks like it wants to sell N different products and confusing flowcharts, but really, you're just geeked out and did something cool and want to share the technical details. So it's designed for the wrong audience.
