[帮助文档] Alibaba Cloud Linux系统中如何通过代码大页功能提升系统的性能

代码大页（Huge Pages）是基于透明大页THP（Transparent Huge Pages）进行的优化扩展，支持将应用程序和动态链接库的可执行部分放入到大页（通常是2 MB或更大）中，有助于降低程序的iTLB miss，并提升CPU的2 MB iTLB利用率，避免内存碎片化或内存膨胀问题，提...

[帮助文档] 通过代码多副本功能避免NUMA架构中跨节点访问延迟

在NUMA架构（尤其是ARM实例）中，不同NUMA节点具有各自的本地内存，当一个NUMA节点上的程序或进程需要访问其他NUMA节点的代码段时，就会引入额外的延迟和性能开销。通过代码多副本功能，可以将远程节点的代码段复制到本地节点，避免了跨节点访问，从而解决NUMA架构中因跨节点访问带来的性能延迟问题...

linux系统安全中通过丢弃处于时间等待状态的套接字的RST数据包来防止time-w的代码是什么？

简单谈一点linux内核中套接字的bind机制--2.6.30内核代码的改进

在2.6.30之前的内核版本中，如果一个要求绑定随机端口的套接字在遍历了所有的哈希表中的元素之后发现没有合适的，那么直接出错返回，这里有几个问题，第一就是如果当前系统的绑定套接字已经足够多了，那么很明显的事实就是等待漫长的遍历结束之后仍然会无功而返，第二个问题就是如果付出了这么大的代价无功而返显然对...
