Enhance read performance tests

- Use cleaner base-data to prevent aready existing exception on generated IDs
- Increased sample size to 10K
- Test 3 scenarios now: get parent, get root and query as all 3 required separate perf improvements
- Adjusted Timing for new size (allowing approx 10% margin in Nordix build)
