比JSON快10倍的序列化包:msgpack Python

MessagePack
MessagePack简称msgpack，官方网站是http://msgpack.org/ ,代码可以在github上查看https://github.com/msgpack。

官方介绍

“Extremely efficient object serialization library for cross-language communication.It’s like JSON, but very fast and small.”

的

从官方的性能测试结果来看，它能够比google protocol buffers快4倍，比json快10倍多。

官方的测试结果是C++的代码，那么Python下的性能又怎么样呢？
python下使用msgpack需要安装

sudo pip install msgpack-python

当然，你也可以通过源码安装，源码地址：https://github.com/msgpack/msgpack-python
