This is not normal. You have some logic that is slowing you down. Trying commenting out bits and pieces of your code that you think are taking a long time and see if that helps. If it does then you need to figure out how to optimize that logic.

If you are doing lots of calculations over a loop iterating through a very large number of objects, then of course it will be slow.

These types of issues can come up in any language or framework. While Ruby is not as fast as other languages, it's fast enough most of the time. If you need to constantly calculate with large data sets then Ruby may not be the right language for you. Look into writing a Ruby C extension that will handle your performance draining code. But first just try to diagnose and refactor.

Lastly, check out RubyProf to see if it can help you find the bottleneck.
