Ruby on Rails is more resource intensive. In part because it uses a framework, and the other part is that Ruby is not really an optimized language yet. In fact benchmarks show running a Ruby interpreter on top of Java actually runs faster than running the Ruby interpreter directly.
As far as it not being able to be used for high traffic sites is a myth. It can, but it will take up more resources. Usually development costs are more than hosting costs so spending another $100 a month on hosting is better than spending another $10,000 on programming. But it's a choice you need to decide. Things can be developed faster in Ruby on Rails but most small scripts would be better written in PHP because Ruby on Rails is designed to do a specific thing well, if you're not doing that it doesn't help.
Do a google for "can rails scale" and if you want more information.
