> For Google it's cheaper to buy 2x as many nodes as it is to make Go gRPC 2x faster. That is definitely not true if Google was using Go gRPC at any reasonable scale. A more accurate conclusion to draw from it is MSFT is using C# gRPC at scale and Google isn't using Go gRPC at scale. Which in itself makes a lot more sense because C# is the bread and butter language at MSFT for most large network services and Go isn't at Google, it barely has any penetration compared to Java and C++ (which predictably have much much faster gRPC and PB implementations).
