About

• a framework，which implements of the modle of AIO BIO NIO and which with optimization of it's buffer.

• it is just depends on the JDK lib, witch with out other libs.

• have done an implementation of proxy which is using this framework.

• 一个网络框架，实现主流的AIO NIO BIO等模型，以及相应的缓存优化

• 框架不依赖JDK外的任何外部LIB

• 在工程中实现了一版基于框架的代理功能

TODO

• protocols interface

• implementations of parser for HTTP protocols and MYSQL protocols

• implementations of recording for the Proxy's logging

• 下一步增加协议接口

• 实现HTTP,MYSQL协议解析

• 代理的日志接口，和实现

First test （proxy）:

ENV

• VM: Xeon E312xx 2.4Ghz X 8 16GB RAM
• MYSQL: 5.7.17
• JAVA: 1.8.74
• NET: VM NETWORKS, ZERO HOP OF ROUTER

DESC

• AIO:
• • 2 thread for R/W handler of server and also for handler of working,
• • 2 thread for R/W handler of client and also for handler of working
• NIO:
• • 1 thread for R/W handler of server,
• • 1 thread for R/W handler of client,
• • n hread for handler of working
• BIO:
• • n thread for R/W handler of server and R/W handler of client and also for handler of working
• NIO(1t):
• • 1 thread for R/W handler of server and R/W handler of client and also for handler of working
• NETTY(1t):
• • 1 thread for R/W handler of server and R/W handler of client and also for handler of working

RESULT

• just directly connecting to Mysql can upto 100K QPS
• the best result is the single thread Proxy(NIO), and it may reach 75K QPS, wich is with low CPU using.
• proxy using BIO may reach 70K QPS , wich is with some CPU using.
• proxy using AIO may reach 70K QPS , wich is with some higher CPU using.
• due to using synchronization in the implementation of the writer, the NIO with 1T + 1T + nT implementation has low QPS, this may improve by changing the strategy.
