Where did the 4–5k RPS come from?

Indicator 4–5k RPS (requests per second) usually arises from load testing analysis or real traffic monitoring. This can be the result of:

• High server performance and optimized code.
• Use of asynchronous or concurrent request processing mechanisms (for example, goroutines in Go).
• Load balancing and scaling architecture.

For example, if a service processes 5000 requests per second, it means that on average, it successfully accepts and responds to 5000 requests every second. Such figures are often achieved through proper infrastructure setup and code optimization.
