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.

ab – slow and single threaded, written in C
apib – most of the features of ApacheBench (ab), also designed as a more modern replacement, written in C
autocannon – fast HTTP/1.1 benchmarking tool written in Node.js
baloo – Expressive end-to-end HTTP API testing made easy, written in Go (golang)

	# Virtustream + RackHD use cases

	Gabi, Rod, and I had a chance to sit down and go over a broad swath of feedback
	related to their use of RackHD in deploying sites. To provide some background,
	they've deployed 8 preliminary sites with RackHD, about 50 nodes each, with a
	target of orchestrating a typical deployment of 200-250 physical compute servers.
	Their configuration has a single RackHD instance per site, and her team (of which
	you'll see Jamie, John & David on the Slack channel) is focused entirely on bare metal
	verification and provisioning and standing up these sites as efficiently as possible.
