Debugging slow Heroku builds

It’s always best to follow a systematic approach when trying to speed up slow code.First, measure the current performance.Next, make the change that you think will help.Lastly, measure again to see if the change worked.It’s no different when it comes to debugging slow test suites or deploys.I recently noticed that my Heroku deploys were taking nearly 10 minutes to build.Thanks to a tip from my friend Anthony, I was able to quickly measure, diagnose, and deploy a fix that shaved nearly 4 minutes off every Heroku build. Big win!.
