Introduction

Once you have your NGINX configuration working, you can turn your focus to fine tuning to enhance performance. A few sections of this chapter will focus on delivering increased performance for users, while others will focus on delivering performance enhancements at a server level to allow greater concurrency.

As with any tuning, you need to ensure that you understand the limits first.

Premature optimization is the root of all evil.

In the context of NGINX, you need to ensure that you know what the limits are before changing them. Not all changes will necessarily result in performance increases if they don't suit your system or if they're not a current limitation.

On the flip side, optimization of your NGINX server is also critical to ensure that your website or application...
