高性能 Nginx HTTPS 调优！为 HTTPS 提速 30%

阅读更多关于高性能 Nginx HTTPS 调优！为 HTTPS 提速 30%

点击上方“ 民工哥技术之路 ”，选择“设为星标” 回复“ 1024 ”获取独家整理的学习资料！为什么要优化 Ngin HTTPS 延迟 Nginx 常作为最常见的服务器，常被用作负载均衡 (Load Balancer)、反向代理 (Reverse Proxy)，以及网关 (Gateway) 等等。一个配置得当的 Nginx 服务器单机应该可以期望承受住 50K 到 80K 左右每秒的请求，同时将 CPU 负载在可控范围内。但在很多时候，负载并不是需要首要优化的重点。比如对于卡拉搜索来说，我们希望用户在每次击键的时候，可以体验即时搜索的感觉，也就是说，每个搜索请求必须在 100ms - 200ms 的时间内端对端地返回给用户，才能让用户搜索时没有“卡顿”和“加载”。因此，对于我们来说，优化请求延迟才是最重要的优化方向。这篇文章中，我们先介绍 Nginx 中的 TLS 设置有哪些与请求延迟可能相关，如何调整才能最大化加速。然后我们用优化卡拉搜索Nginx 服务器的实例来分享如何调整 Nginx TLS/SSL 设置，为首次搜索的用户提速 30% 左右。我们会详细讨论每一步我们做了一些什么优化，优化的动机和效果。希望可以对其它遇到类似问题的同学提供帮助。 TLS 握手和延迟很多时候开发者会认为：如果不是绝对在意性能，那么了解底层和更细节的优化没有必要。这句话在很多时候是恰当的
