A user complains that the report has become slow (2-3 minutes instead of 30-40 seconds). What questions will you ask and how will you gather information for analysis?

To analyze the cause of report slowdown, detailed information needs to be gathered. Questions and steps:

1. When did the slowdown start?

   • Were there any changes in code, data, or infrastructure?

2. How often and under what conditions does the problem occur?

   • Is it constant or periodic?
   • Does it happen on all devices and for all users?

3. Data volume:

   • Has the volume of data processed by the report increased?

4. Environmental changes:

   • Software updates, database, servers?

5. Logs and metrics:

   • Collect report execution logs, timing of individual stages
   • Monitor server load, resource usage (CPU, memory, disk, network)

6. Technical details:

   • What database is used?
   • Are indexes used, are queries optimized?

7. Code review:

   • Have there been changes in report logic?

8. Reproduction of the problem:

   • Can the slowdown be reproduced in a test environment?

Gathering information can start with user interviews, then proceed to log analysis and monitoring, check for system and data changes. This will help localize the problem and determine further steps for optimization.
