Just running `irb` with no libraries is 9.9 mb for me with Ruby 2.2.3. In Ruby 2.0 it's 17.9mb for me. Ruby is not known to be the most memory efficient language. 




I wrote a tool to help debug memor use in apps, check it out https://github.com/schneems/derailed_benchmarks




You can run 




$ derailed bundle:mem




To see the memory impact of all the gems you're using at require time.
