Demo of the potential of C# for systems programming with the .NET native ahead-of-time compilation technology.
One thing I'd like to add as a potential differentiator as well is that YARP runs very well on Windows and because it's build on ASP.NET Core, can run inside of IIS and directly on HTTP.sys as well (which means we can take advantage of cool features like http.sys request delegation where possible https://github.com/microsoft/reverse-proxy/commit/b9c13dbde9...). This means you get platform portability AND deep platform integration for free.
mdasen has already pointed out that "2x" seems to overstate the difference by quite a bit. YARP also has a spikier max latency, which I'd expect for a GC'ed language.
I don't see a way to choose the benchmarking platform in the PowerBI dashboard, so I assume all these numbers were collected on Windows. In that case, it doesn't surprise me that YARP is faster: Envoy uses libevent for cross-platform I/O, but libevent is far from ideal on Windows. As I understand it, the libevent backend that uses I/O completion ports is relatively slow _and_ it exposes a BSD-style socket API, which forces Envoy to manage buffers rather than delegating that to IOCP. Kestrel, YARP's underlying webserver, uses libuv instead. libuv is more actively developed (because of Node.js) and takes the opposite approach, exposing an IOCP-like API even on POSIX systems. This Envoy issue[0] is really informative if you're interested in the details. Basically, YARP's I/O model is much closer to Windows' native model, so it wouldn't surprise me if it's competitive with Envoy's performance.
More broadly, the .NET team that builds the Kestrel webserver and contributes to YARP and gRPC is full of performance heavyweights. I wouldn't want to compete head-to-head with James Newton-King, David Fowler, and the other folks on that team, and I'd start by assuming that the benchmarks for their projects are thoughtfully designed. Everyone makes mistakes, but start by assuming that they're brilliant engineers leading a talented team - because they are.
I say all this as someone who doesn't particularly love Windows as a development environment, .NET as a language, or Microsoft as a company (quit after just 6 months). Credit where credit's due.

I never thought I'd laud microsoft on open source software but this has certainly made my life easier... I mean come on, MIT licensed and everything...

Worth noting that YARP (or as someone has eloquently described it as PRAY) here was another Microsoft project which basically killed a previous open source project which did the same thing:
https://github.com/proxykit/ProxyKit
It already is a systems language and has been since the outset. Managed code is the preference, but you can certainly run unmanaged code with direct memory access if you want to.
