Most setup guides for Nginx tell you the basics - apt-get a package, modify a few lines here and there, and you’ve got a web server! And, in most cases, a vanilla nginx install will work just fine for serving your website. However, if you’re REALLY trying to squeeze performance out of nginx, you’ll have to go a few steps further. In this guide, I’ll explain which settings in nginx can be fine tuned in order to optimize performance for handling a large number of clients. As a note, this isn’t a comprehensive guide for fine-tuning. It’s a breif overview of some settings that can be tuned in order to improve performance. Your mileage may vary.
