How can you measure and report the impact of your performance tuning efforts?

2 Test and validate

After you have identified and implemented the performance tuning changes, you need to test and validate them to ensure that they work as intended and do not introduce any errors or side effects. You can use the same tools and metrics that you used for the baseline and benchmark, but you should also consider using a different environment, such as a staging or testing server, to avoid affecting the production database. You should also run the same or similar queries or workloads that you used for the baseline and benchmark, to ensure a fair comparison. You should also document your test and validation results, as well as any issues or challenges that you encountered.

3 Compare and report

Once you have tested and validated your performance tuning changes, you need to compare and report them to your baseline and benchmark. You can use tools such as SQL Server Performance Dashboard, Oracle ADDM, or MySQL Performance Schema to generate graphical or tabular reports that show the before and after performance metrics, as well as the percentage of improvement or degradation. You can also use tools such as SQL Server Data Collector, Oracle Statspack, or MySQL Enterprise Monitor to track and monitor the long-term performance trends and patterns of your database. You should also document your comparison and report results, as well as any recommendations or feedback that you have for further tuning or maintenance.

4 Communicate and educate

Finally, you need to communicate and educate your stakeholders, clients, or managers about the impact of your performance tuning efforts. You should use clear and concise language, as well as visual aids, such as charts, graphs, or screenshots, to explain the problem, the solution, and the results of your tuning activities. You should also highlight the benefits and value of your tuning efforts, such as faster response time, higher throughput, lower resource consumption, fewer errors, or happier users. You should also educate your audience about the best practices and tips for maintaining and improving the database performance, such as regular backups, indexes, statistics, or audits. You should also solicit feedback and suggestions for future tuning or improvement opportunities.
