How we spent $30k in Firebase in less than 72 hours
When you have an unexplained performance problem, your response shouldn't be to "upgrade every single framework and plugin" that you use. The 36 hours that they spent doing this cost them $21,600 dollars on GCP and didn't solve their users' problem.Understand the services you depend on. Track the number of requests you're making to them, how long they're taking, and how many are failing. Reason through your system and look at the data when you have issues, rather than grasping at straws.
