解读io.netty.util.Recycler

本文介绍Netty中的Recycler轻量级对象池实现原理,它使用Thread-Local来为每个线程提供独立的对象栈,通过复用ChannelOutboundBuffer对象减少频繁创建与垃圾回收带来的开销。

netty使用基于thread-local的轻量级对象池Recycler对ChannelOutboundBuffer进行回收。当ChannelOutboundBuffer第一次被实例化且使用完毕后,会回收到Recycler中(见下面的recyle方法),下次需要用时,直接从Recycler中取(见下面的get方法),避免了再次实例化和垃圾回收的开销。
