What performance metrics did you use to evaluate your last project?

When evaluating the effectiveness of work on the last Go project, I used the following metrics:

• Service response time (latency) — how quickly requests are processed.
• Throughput — the number of requests processed per second.
• Resource usage (CPU, memory) — to ensure the application operates efficiently and does not overload the system.
• Number of errors and failures — to assess stability.
• Time to execute key business processes — to understand how effectively the logic is implemented.

These metrics helped identify bottlenecks and improve the application's performance and reliability.
