Cache-money plugin: your thoughts

Hello.

I would like to get some feedback from people using the “cache-money”
plugin: https://github.com/nkallen/cache-money

We are seriously considering using it in our production environment.
Couple of questions (if you are using this in production):

  1. Has your performance improved?
  2. Have you noticed any weird problems?
  3. Any other comments?

Thanks in advance.

Ben
