What signs indicate that a query is running slower than expected?

To determine that a request is running slower than expected, you can look for the following signs:

• High response time: the measured request execution time significantly exceeds the average or expected time.
• Logging of time: if logs record a long processing time for the request.
• Timeouts: frequent timeouts during request execution.
• Monitoring and metrics: monitoring indicators (e.g., Prometheus, Grafana) show an increase in latency.
• User complaints: users report delays or freezes.

In Go, you can measure the request execution time using the time package:

start := time.Now()
// execute request
elapsed := time.Since(start)
fmt.Printf("Request execution time: %s\n", elapsed)

If elapsed is significantly greater than expected, the request is slow.
