Where does such a high RPS come from?

High RPS (requests per second) can be caused by several reasons:

• High user load: the application may be serving a large number of clients or requests.
• Automated scripts or bots: external or internal processes might generate many requests.
• Errors in code or configuration: for example, infinite loops, repeated requests, or incorrect caching.
• Peak operation periods: times of day or events that cause a surge in activity.
• Incorrect monitoring: metrics might be counted incorrectly, for example, repeated requests or internal calls are considered.

To accurately identify the source, it is necessary to analyze logs, metrics, traces, and possibly conduct application profiling.
