Proposed changes

Just found one more thing to cache ;) Also thought about combining it with PipelineConfig but thought this one is clearer to understand and also with less changes

This is pretty insane! I would not have thought that viper has such a slow retrieval process! I think we should probably introduce caching to viper itself because this really isn't acceptable performance-wise!

Thank you for this change :)
