What does the RPS metric indicate and how does it affect system performance?

RPS (Requests Per Second) is a metric that reflects the number of requests processed by the system per second.

Impact of RPS on performance:

• High RPS indicates a high load and requires the system to have high throughput.
• If the system cannot handle the increase in RPS, response times increase and request loss may occur.
• Monitoring RPS helps determine when to scale the system or optimize processing.

For example, a web server with an RPS of 1000 processes 1000 requests per second. If RPS suddenly increases, it is necessary to ensure that the server and database can handle such a load without performance degradation.
