grpc_byte_buffer_reader_next() copies and references the slice. This
is not always necessary since the caller will not use the slice
after destroying the byte buffer.
A prominent example is the protobuf parser, which
calls grpc_byte_buffer_reader_next() and immediately unrefs the slice
after the call. This ref() and unref() calls can be very expensive
in the hot path.
This commit introduces grpc_byte_buffer_reader_peek() which
essentialy return a pointer to the slice in the buffer, i.e.,
no copies, and no refs.
QPS of 1MiB 1 Channel callback benchmark increases by 5%.
More importantly insructions per cycle is increased by 10%.
Also add tests and benchmarks for byte_buffer_reader_peek()

gRPC - An RPC library and framework
gRPC is a modern, open source, high-performance remote procedure call (RPC) framework that can run anywhere. gRPC enables client and server applications to communicate transparently, and simplifies the building of connected systems.
| Homepage: | grpc.io |
| Mailing List: | grpc-io@googlegroups.com |
To start using gRPC
To maximize usability, gRPC supports the standard method for adding dependencies to a user's chosen language (if there is one). In most languages, the gRPC runtime comes as a package available in a user's language package manager.
For instructions on how to use the language-specific gRPC runtime for a project, please refer to these documents
- C++: follow the instructions under the
src/cppdirectory - C#: NuGet package
Grpc - Dart: pub package
grpc - Go:
go get google.golang.org/grpc - Java: Use JARs from Maven Central Repository
- Node:
npm install grpc - Objective-C: Add
gRPC-ProtoRPCdependency to podspec - PHP:
pecl install grpc - Python:
pip install grpcio - Ruby:
gem install grpc - WebJS: follow the grpc-web instructions
Per-language quickstart guides and tutorials can be found in the documentation section on the grpc.io website. Code examples are available in the examples directory.
Precompiled bleeding-edge package builds of gRPC master branch's HEAD are uploaded daily to packages.grpc.io.
To start developing gRPC
Contributions are welcome!
Please read How to contribute which will guide you through the entire workflow of how to build the source code, how to run the tests, and how to contribute changes to the gRPC codebase. The "How to contribute" document also contains info on how the contribution process works and contains best practices for creating contributions.
Troubleshooting
Sometimes things go wrong. Please check out the Troubleshooting guide if you are experiencing issues with gRPC.
Performance
See the Performance dashboard for performance numbers of the latest released version.
Concepts

| Shared C [core library] | src/core |
| C++ | src/cpp |
| Ruby | src/ruby |
| Python | src/python |
| PHP | src/php |
| C# | src/csharp |
| Objective-C | src/objective-c |
| Language | Source repo |
|---|---|
| Java | grpc-java |
| Go | grpc-go |
| NodeJS | grpc-node |
| WebJS | grpc-web |
| Dart | grpc-dart |
