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（Hugetext）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，提高内存利用效率，适用于数据库、大型应用程序等大代码段业务场景。本文主要介绍代码大页的使用方法以及性能收益...

通过代码多副本功能避免NUMA架构中跨节点访问延迟_Alibaba Cloud Linux(Alinux)

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。
