NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

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.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

	# Please note, the commands below will create unreadable files and should be
	# used for testing file size only. If you're looking for something that has
	# lines in it, use /dev/urandom instead of /dev/zero. You'll then be able to
	# read the number of lines in that file using `wc -l large-file.1mb.txt`

	# Create a 1MB file
	dd if=/dev/zero of=large-file-1mb.txt count=1024 bs=1024

	# Create a 10MB file
	dd if=/dev/zero of=large-file-10mb.txt count=1024 bs=10240

	user web;

	# One worker process per CPU core.
	worker_processes 8;

	# Also set
	# /etc/security/limits.conf
	# web soft nofile 65535
	# web hard nofile 65535
	# /etc/default/nginx
