How fast is Envoy on Windows?

Note

On August 31, 2023 the Envoy project ended official Windows support due to a lack of resources. We will continue to accept patches related to the Windows build. Until further notice, Windows builds are excluded from Envoy CI, as well as the Envoy release and security processes.

Everything that is mentioned in How fast is Envoy? applies to Windows. We have done some work to improve the event loop on Windows. That being said, we have observed that the tail performance of Envoy on Windows tends to be worse compared to Linux, especially when TLS is involved.

We are actively investigating performance and aim to improve on a continuous basis.
