Excessive Redis calls

[fosron]

Hey,

I think this method should not call cache in any kind of production environment. I understand safe guarding while development is happening, but excessive connections to cache server (if it is Redis or any other) seems redundant.

I would suggest either a master switch for this check, an environment config, or altogether removing this method.
