Can Spring Boot Really Handle 1 Million Requests Per Second?
Everyone asks if Spring Boot can handle 1M RPS. That’s the wrong question — here’s the one that actually matters.
The answer has much less to do with Spring Boot than you might think.
Imagine your API suddenly starts receiving 1 million requests every second.
At first, the obvious question is:
“Can Spring Boot handle that much traffic?”
But that’s actually the wrong question.
At that scale, your application framework is only one small part of the system.
The load balancer, network, JVM, CPU, database, cache, external APIs, connection pools, serialization, and deployment architecture all become part of the performance equation.
And there is an important distinction:
A single Spring Boot server handling 1 million requests per second is a completely different problem from a Spring Boot-based system handling 1 million requests per second.
The second is achievable with the right architecture.
The first is usually not the goal.
