AI Summary: Investigate and resolve a significant performance regression in an AsyncIO event loop implementation (RLoop) when used with Uvicorn on Linux. The issue causes a 4-6x slowdown compared to the standard library and uvloop, and is not present on MacOS. Debugging will require familiarity with Rust, AsyncIO, and potentially low-level networking.
