Reading time 9 min When it comes to managing web performance, it’s vital to be proactive rather than reactive. To accomplish this goal, an organization needs to build internal processes and procedures that can operationalize a performance-first culture. The first step is to establish and implement web performance budgets. According to Tim Kadlec : A performance budget is a clearly defined limit on one or more performance metrics that the team agrees not to exceed and that is used to guide design

By having appropriate indexes on your MySQL tables, you can greatly enhance the performance of SELECT queries. But, did you know that adding indexes to your tables in itself is an expensive operation, and may take a long time to complete depending on the size of your tables? During this time, you are also likely to experience a degraded performance of queries as your system resources are busy in index-creation work as well.
