Io_uring, kTLS and Rust for zero syscall HTTPS server

Unfortunately io_uring is disabled by default on most cloud workload orchestrators, like CloudRun, GKE, EKS and even local Docker. Hope this will change soon, but until then it will remain very niche.

Why do they disable io_uring?

Sandboxing like gvisor is based on syscalls and iouring makes your code syscallless
