zerg is a low-level TCP framework built directly on Linux io_uring with zero-copy buffer rings, multishot accept/recv, and DEFER_TASKRUN optimizations. This entry builds a full HTTP/1.1 server on top using the PipeReader adapter for pipelining support. Interesting comparison with aspnet-minimal: same .NET runtime but radically different I/O strategy (io_uring vs Kestrel). - Language: C# - Engine: io_uring via liburing shim - Tests: baseline, noisy, pipelined, limited-conn, json, upload, compression, mixed

zerg — C# on raw io_uring
zerg is a low-level TCP server framework for C# built directly on Linux
io_uring. Zero-copy buffer rings, multishot accept/recv,DEFER_TASKRUN/SINGLE_ISSUER— no HTTP abstractions, just raw TCP with async/await.Why this is interesting
HttpArena already has
aspnet-minimal(Kestrel) — this is the same language, completely different I/O strategy comparison. Kestrel uses epoll/libuv abstractions; zerg goes straight to io_uring with provided buffer rings. How much does skipping the HTTP framework stack and using io_uring directly buy you in C#?Implementation

cc @MDA2AV — since zerg is your project, figured it'd be cool to see how it stacks up against Kestrel in HttpArena! The C# io_uring vs epoll comparison should be really interesting.
