Finding Candidates for Query Optimizations
- Making use of The Performance Schema, which is a gold mine for spotting querying for optimization because it allows us to measure where the time goes
- Finding the few queries that are responsible for most of the load on the system. Checking the top 1000 queries it’s usually not worth your time to optimize.
