If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.
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:
| # Building static nginx for teh lulz | |
| # | |
| # basic dependencies | |
| sudo apt-get install libxslt1-dev libxml2-dev zlib1g-dev libpcre3-dev libbz2-dev libssl-dev | |
| # download nginx and openssl | |
| wget http://nginx.org/download/nginx-1.5.6.tar.gz | |
| tar xf nginx-1.5.6.tar.gz; cd nginx-1.5.6 |
Create a Meteor app and put the client_/server_ files in a client/server directories. Also, create a public dir to save the uploaded files.
| # Install MacTex: http://mirror.ctan.org/systems/mac/mactex/mactex-basic.pkg | |
| $ sudo chown -R `whoami` /usr/local/texlive | |
| $ tlmgr update --self | |
| $ tlmgr install ucs | |
| $ tlmgr install etoolbox | |
| # Install pandoc view homebrew |

| Mutex lock/unlock 25 ns | |
| Main memory reference 100 ns 20x L2 cache, 200x L1 cache | |
