If you can afford, upgrade your CI runners on GitHub to paid offering. Highly recommend, less drinking coffee, more instant unit test results. Pay as you go.
As a Depot customer, I'd say if you can afford to pay for GitHub's runners, you should pay for Depot's instead. They boot faster, run faster, are a fraction of the price. And they are lovely people who provide amazing support.
This is what we focus on with Depot. Faster builds across the board without breaking the bank. More time to get things done and maybe go outside earlier.
