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

	# To recap, the best way (I've found) to completely uninstall node + npm is to do the following:

	# go to /usr/local/lib and delete any node and node_modules
	cd /usr/local/lib
	sudo rm -rf node*

	$ git status # 检查文件当前的状态

	$ git diff --cached # 若要看已经暂存起来的文件和上次提交时的快照之间的差异
	$ git commit -m "Story 182: Fix benchmark" # 用一行命令提交更新
	$ git commit -a -m 'added new benchmarks' # 跳过add命令直接提交
	$ git rm --cached log.log # 从git仓库中删除不小心追踪的文件（用于gitignore之前追踪的文件）
	$ git mv file_from file_to # 移动文件/重命名文件
