Code reviews seem to be a blocker on our team ever since. It is big, it takes time and it slows our delivery. Personally, I am having difficulty giving feedbacks and comments. I am torn on enforcing code standards and suggesting practices, and reducing frustrations for the developer. We are , most of the time, fast-paced so the developer usually have another task to work on. I feel like I am being the blocker by giving too many feedbacks when the developer should have moved on to another task.

How do you do it with your team? Quality of the code or quality of the human code? Where is the balance?
