Linux内核27-优化和内存屏障

1. 引言我们都知道，带有优化的编译器，会尝试重新排序汇编指令，以提高程序的执行速度。但是，当在处理同步问题的时候，重新排序的指令应该被避免。因为重新排序可能会打乱我们之前想要的同步效果。其实，所有的同步原语都可以充当优化和内存屏障。优化屏障保证屏障原语前后的C语言转换成汇编语言之后，指令序列不会发...

linux操作系统网络内核优化

Linux系统下，TCP连接断开后，会以TIME_WAIT状态保留一定的时间，然后才会释放端口。当并发请求过多的时候，就会产生大量的TIME_WAIT状态的连接，无法及时断开的话，会占用大量的端口资源和服务器资源。这个时候我们可以优化TCP的内核参数，来及时将TIME_WAIT状态的端口清理掉。...
