Netty问题小结 1.问题:高并发时连接不够:java.net.SocketException: No buffer space available (maximum connections reached?): connect 解决办法: socket.setSoLinger(true, 0);设置socket.close()方法调用后立即释放占用的端口 2.java.io.IOException: 远程主机强迫关闭了一个现有的连接。 在Socket客户端获取Socket...
注意:频繁连接服务器建立1w个连接,即使全部断开,在客户端netstat –p依然可以看到这2w个端口在被占用着,未完全释放。这时就会出现异常 java.net.SocketException: No buffer space available (maximum connections reached?): connect 3. 分别在单个连接和多个连接的情况下,统计服务器端netty网络层的吞吐率。 单连接 ...

Memory management: arena. Memory is managed by a certain number of arenas. Each user thread uses round-robin polling to select an available arena for memory allocation. Hierarchical management:bin. The memory size managed by each bin increases by category. The allocation of small and medium memor...

it will tell the other party the size of its receiving window, which is the remaining free space in the buffer. If the receiving window size is zero, it means that the receiver's buffer is full, and the sender will no longer send data until the client clears its internal buffer, and ...
