Benchmarking Nginx with Go

There are a lot of ways to serve a Go HTTP application. The best choices depend on each use case. Currently nginx looks to be the standard web server for every new project even though there are other great web servers as well. However, how much is the overhead of serving a Go application behind an nginx server? Do we need some nginx features (vhosts, load balancing, cache, etc) or can you serve directly from Go? If you need nginx, what is the fastest connection mechanism? This are the kind of questions I'm intended to answer here. The purpose of this benchmark is not to tell that Go is faster or slower than nginx. That would be stupid.

So, these are the different settings we are going to compare:

Go HTTP standalone (as the control group)
Nginx proxy to Go HTTP
Nginx fastcgi to Go TCP FastCGI
Nginx fastcgi to Go Unix Socket FastCGI

	# xcode-build-bump.sh
	# @desc Auto-increment the build number every time the project is run.
	# @usage
	# 1. Select: your Target in Xcode
	# 2. Select: Build Phases Tab
	# 3. Select: Add Build Phase -> Add Run Script
	# 4. Paste code below in to new "Run Script" section
	# 5. Drag the "Run Script" below "Link Binaries With Libraries"
	# 6. Insure that your starting build number is set to a whole integer and not a float (e.g. 1, not 1.0)
