Why is Nginx slow?

Responses that don't fit in memory are written to disk, which can slow performance. When NGINX buffering is on, you use the proxy_buffer_size and proxy_buffers directives to manage it. Client keepalives – Keepalive connections reduce overhead, especially when SSL/TLS is in use.

How many RPS can Nginx handle?

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

Is Nginx fast?

We've done some benchmarks for CMS systems such as Wordpress, Drupal, Joomla, TYPO3, etc., and the result is that NGINX delivers pages up to 50% faster than Apache. At the same time NGINX can handle up to 177% as many requests per second (RPS) as Apache.

How much RAM does Nginx need?

Nginx is excellently optimized and requires very few memory and disk. Master process of nginx can require about 16MB and about 100–300MB for each worker, later depends on your configuration, first of all on caches. If you do not plan very big load and caching 128 MB should be enough.

Can Nginx do load balancing?

Nginx, a popular web server software, can be configured as a simple yet powerful load balancer to improve your servers resource availability and efficiency. ... Nginx acts as a single entry point to a distributed web application working on multiple separate servers. This guide describes the advantages of load balancing.

What Nginx used for?

NGINX is open source software for web serving, reverse proxying, caching, load balancing, media streaming, and more. It started out as a web server designed for maximum performance and stability.

Does a reverse proxy slow down?

This buffering reverse proxy can handle an “unlimited” number of requests, and is not affected by slow clients.

What is Keepalive_timeout in nginx?

The keepalive_timeout assigns the timeout for keep-alive connections with the client. Simply put, Nginx will close connections with the client after this period of time.

What is Nginx rate limit?

One of the most useful, but often misunderstood and misconfigured, features of NGINX is rate limiting. It allows you to limit the amount of HTTP requests a user can make in a given period of time. ... Rate limiting can be used for security purposes, for example to slow down brute‑force password‑guessing attacks.

What is burst in nginx?

Based on the excellent Dan's answer and on the source code of nginx, a concise summary for the nodelay behavior seems to be the following: burst is how many new concurrent requests are allowed. rate is how many new concurrent requests become old per unit of time.

How do I limit Nginx connections?

Using NGINX and NGINX Plus, it is possible to limit:

1. The number of connections per key value (for example, per IP address)
2. The request rate per key value (the number of requests that are allowed to be processed during a second or minute)
3. The download speed for a connection.
