mongols-0.9.2 发布，C++ 服务器基础设施

mongols-0.9.2已经发布。

主要更新：

• 添加zstd库

• 为http server优化会话和缓存管理

介绍：

mongols是一个主要针对c++服务器端开发的基础设施库。主要特性如下：

• tcp sever (epoll)

• tcp multi-threading server (epoll+multi-threading)

• http server (epoll)

• http multi-threading server (epoll+multi-threading)

• websocket server (epoll+multi-threading)

• utils

依赖：

• linux

• gcc(c11)，g++(c++11)

• pcre-devel

• zlib-devel

• openssl-devel

sudo yum install pcre-devel zlib-devel openssl-devel

或者：

sudo apt-get install libpcre3-dev zlib1g-dev libssl-dev

安装：

make clean && make -j2 && sudo make install && sudo ldconfig

使用：

pkg-config --libs --cflags mongols

例子：

#include <mongols/tcp_server.hpp>
#include <mongols/tcp_threading_server.hpp>
#include <mongols/http_server.hpp>
#include <mongols/ws_server.hpp>
#include <mongols/util.hpp>
#include <iostream>

			keepalive = KEEPALIVE_CONNECTION;
			send_to_other=true;
			return input;
	};
	server.run(f);
	server.run();
}

	mongols::http_server 
	//server(host,port,5000,1024,4);
	server(host,port);
	server.set_enable_session(false);
	server.set_enable_cache(false);
	server.run(f,g);
}

压力测试：

2核4G，centos7

ab -c1000 -n100000 http://127.0.0.1:9090/

RPS: 10000+

ab -kc1000 -n100000 -H'Connection: keep-alive'   http://127.0.0.1:9090/

RPS: 50000+

在ubuntu 18.04上RPS更高，keep-alive，高达80000-120000。
