I didn't expect gRPC-web to surpass the performance of normal Web API endpoints. The asp.net core team has spoken a number of times about how they are still refining HTTP2 performance, these numbers might look completely different once. An array of some numeric data type would be more interesting. Two of your larger requests are string, but that is the worst data type to send/receive to compare JSON and protobuf (they both serialize that type similarly). Message brokers (e g NATS, Rabbit) provide a higher-level abstraction in which a client sends messages to an intermediate service called a broker (this could be done using gRPC) and the broker may queue messages and either ship them directly to services (push) or wait for a service to check its subscription (pull).This can make a huge performance difference, especially if the console log isn't turned off when debugging. You don't mention what configuration this was run in, or if it was with a debugger attached or not.100 concurrent requests isn't likely to use enough CPU for the difference in CPU usage of serialization to matter at all.NET Core Reusing and Recycling Data Structures in gRPC Services in. NET Core Defining Your First gRPC Service in an ASP.NET Core 3.0 Project Writing the Code for a gRPC Service and Client in ASP.NET Core 3.0 Dont Do It All Yourself: Exploiting gRPC Well Known Types in.

This might possible explain the odd results in #4 How to Design Messages for gRPC Services in. Zenesys is a leading software development company based in USA & India. This cap likely doesn't exist for signalR using a web socket. I think Chrome caps HTTP2 at 100 (the HTTP1.1 value is much lower). Browsers still have a maximum number of active requests. The browser isn't actually doing 1000 concurrent requests.Is the browser using HTTP2 for REST and gRPC-web? I see details about IIS in launchSettings, but you don't mention if the environment you ran this code meets the requirements for HTTP2 in IIS. Ambiguity about how this test is hosted.This would affect the results of #1 the most. In contrast, gRPC APIs are delivered over HTTP/2 and support several. Using a local connection instead of a bandwidth constrained one negates most of the benefit of using protobuf (the smaller sizes). REST APIs support a request-response model with limited support for streaming. In my session, I will cover what REST, GraphQL, and gRPC are, how APIs can be implemented using. REST, GraphQL and gRPC are three main options when it comes to API development and implementation. ![]() Each of them has its own characteristics, patterns of data exchange, pros, and cons. You appear to be using localhost for this test ( Properties/launchSettings.json ). Over time, different API architectural styles have been released.
