One of the biggest myths in software engineering is that growth inevitably makes software slower.
We almost expect it.
More users mean more database queries. More requests mean more servers. More features mean more bugs. Eventually someone says, "We'll optimize it later," and everyone silently agrees that the application will only get slower from here.
But when you study companies like Google, Netflix, Discord, Amazon, Stripe, and Cloudflare, something interesting appears.
Many parts of their systems actually become faster as they grow.
