I rewrote my DNS checking tool (http://www.dnsinspect.com/) in Go and I saw huge differences in resource usage (previously it was implemented with Ruby on Rails + EventMachine), my memory usage went down from 128MB per background worker to a few KB.

Now I'm able to run hundreds to thousands of concurrent reports using a small VPS, the Go application is using 36MB of RAM (24MB front end + 12MB for background workers). Go language is well suited for my particular case (many concurrent IO operations).

This was my first Go project, in a week I was comfortable with it, I had many alternatives but I really liked the simplicity of Go, fast compilation and easy of deployment. Because I've missed some pieces from the Ruby's world I've combined Jekyll (Compass, HAML SASS, RedCarpet, etc) with Go. :)

Do you also used the default net/http support libraries?

[vitalie]

Yes, I'm using net/http.
