How much RAM does nginx use?
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.
How much memory and CPU does nginx need?
At idle expect ~10MB of memory for both containers and ~0 CPU usage 🙂 You should not exceed 128MB for the nginx, unless you plan to enable content caching. As for the node container, 512MB should be more than enough.
How many requests can nginx handle per second?
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.
How fast is nginx?
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 is nginx fast?
nginx is much faster than Apache, but this merely means the site owner will need fewer servers for the web serving part — nginx does not transfer data faster to you. The less important part is server-side speed, i.e. the time it takes to create the HTML.
How make nginx faster?

- Configure Worker Processes to Improve Speed.
- Configure Worker Connections.
- Configure Buffers Size.
- Configure Timeouts.

Why does Nginx use so much memory?
It may be that we allocate some Nginx shared memory zones way too big and they may someday bite us badly when they actually get filled up with data (in which case they would become part of the Resident Memory component). We will cover resident memory in more detail in another article. Next let’s take a look at memory usage on the application level.
What is requests per second (rps) in Nginx?
Requests per second (RPS) measures the ability to process HTTP requests. Each request is sent from the client machine to the NGINX web server. The tests were done for both unencrypted HTTP and encrypted HTTPS traffic.
How many Nginx worker processes can I run at once?
worker_processes – The number of NGINX worker processes (the default is 1). In most cases, running one worker process per CPU core works well, and we recommend setting this directive to auto to achieve that.
How many file descriptors can Nginx use per connection?
NGINX can use up to two file descriptors per connection. For example, if NGINX is proxying, it generally uses one file descriptor for the client connection and another for the connection to the proxied server, though this ratio is much lower if HTTP keepalives are used.
