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

Introduction

Chef is a Ruby framework for automating, reusing and documenting server configuration. It's like Unit tests for your servers.

	"auto_complete_commit_on_tab": true,
	"auto_complete_delay": 0,
	"bold_folder_labels": true,
	"caret_style": "wide",
	"color_scheme": "Packages/User/Monokai (SL).tmTheme",

	In this step, we need to choose the physical volumes that will be used to create the LVM. We can create the physical volumes using pvcreate command as shown below.
	1- pvcreate /dev/xvde /dev/xvdf
	pvscan pvdisplay

	Volume groups are nothing but a pool of storage that consists of one or more physical volumes. Once you create the physical volume, you can create the volume group (VG) from these physical volumes (PV).
	In this example, the volume group vol_grp1 is created from the two physical volumes as shown below

	2- vgcreate datavol /dev/xvde /dev/xvdf

	vgdisplay

	Install and configure JAVA + MAVEN in Ubuntu 14.04
	It's pretty easy to install and configure JAVA + MAVEN in Ubuntu 14.04 following these steps:

	1. Install OpenJDK 7:

	$ sudo apt-get install icedtea-7-plugin openjdk-7-jre openjdk-7-jdk

	Check the installed java:

	$ java -version

	include $(GOROOT)/src/Make.inc

	GOFMT=gofmt -spaces=true -tabindent=false -tabwidth=4

	all:
	$(GC) jsontest.go
	$(LD) -o jsontest.out jsontest.$O

	format:
	$(GOFMT) -w jsontest.go
