What It Shows
- Execution time for each statement.
- Rows returned vs. rows scanned (when Oracle provides stats).
- Client-side render time (how long the grid took to display data).
Using the Monitor
- After running a query, open the Performance tab in the results pane.
- Toggle Show timeline to see how long each phase (prepare, fetch, render) took.
- Use the info to decide whether you need indexes, filters, or smaller result sets.
Alerts
- Koala flags queries that run longer than your configured threshold (default 30 seconds) and suggests options:
- Cancel the query
- Export instead of rendering
- Refine filters
Tips
- Combine with SQL History to compare performance over time.
- Export the performance log (JSON) when filing support tickets so admins can analyze slow statements.
