You don’t always need a faster API — just a smarter cache.

Most developers chase performance using async code or scaling —

but forget one simple hero: Response Caching Middleware.

Your APIs might be regenerating the same response thousands of times a day.

That means wasted CPU, slower latency, and higher cloud bills.

I enabled response caching in a test ASP.NET Core app —

and cut average response time by almost 40% for static GET requests.

With a few lines of middleware and correct cache headers,

.NET can reuse cached responses instantly, skipping backend work.

Do you cache your API responses — or let every request hit the server?

When was the last time you tested your caching strategy?
