Nginx is a web server, load balancer and reverse proxy with a strong focus on performance, high concurency (over 10,000 simultaneous connections), and low memory usage. In this tutorial, we will use Nginx as the web server that only supports the Layer 7 HTTP mode. It also has a proof of concept port for Microsoft Windows. Nginx [pronounced "Engine X"] is an HTTP and reverse proxy server that emphasizes high concurrency, performance, and low memory usage. According to Dreamhost Wiki, Below graphical representation of memory usage clearly shows that NginX has minimum memory consumption. In Nginx, memory consumption is very low for serving static pages. The server process free the global variables table, the exception flag and the byte-code which cause the increase of memory usage mainly, in order to reduce the memory usage and extend safely by preventing interference between each scripts because of sharing the region. You need turn on the swap then optimize apache, mysql configuration to decrease the memory usage. If a Container is created in a namespace that has a default memory limit, and the Container does not specify its own memory limit, then the Container is assigned the default memory limit. If that's the case, make sure to explicitly set the desired number in the worker_processes directive. For instance, if --memory="300m" and --memory-swap is not set, the container can use 600m in total of memory and swap. The top command can display system summary information as well as a list of the process currently being. NGINX is event-based, which means that it does not need to spawn a new thread or process for each request. The expire directive instructs the browser to expire file cache after a certain amount of time (or at a certain time). Their system resource usage (CPU, RAM and I/O) is reduced. htaccess for nginx enables nginx high performance webserver to deal with. Now that I understand this better, I am not sure my approach will help much with memory consumption. Requests per second. Monitor the CPU Usage, memory used, number of threads used, by abhilash.

Examples: (I) memory ups and downs are more ordered and appear less volatile, (II) memory increase and decrese changed from "curves" to steps, as if nginx worker processes simultanously freed memory or simultanously increased memory, (III) more even CPU usage, even under extreme load (no matter how extreme the load). Flask documentation is very clear on where is the place for its built-in WSGI application server: While lightweight and easy to use, Flask’s built-in server is not suitable for production as it doesn’t scale well and by default serves only one request at a time.
