The developer reports that one of the work stages takes significantly longer than before, even though there have been no changes in the code. What reasons could explain this difference?

If a work stage takes significantly longer without changes in the code, possible reasons may include:

• Environment changes: OS updates, libraries, drivers that affect performance.
• Infrastructure load: other processes or users consuming resources (CPU, memory, disk, network).
• Hardware issues: disk degradation, network problems, overheating.
• Data changes: increased volume or complexity of processed data.
• External dependencies: slowing down of databases, APIs, or other services.
• Configuration changes: environment parameters, timeout settings, limits.

To diagnose, check system metrics, logs, load, hardware status, and compare with previous periods.
