Navicat Monitor is an agentless remote server monitoring tool that is packed with powerful features to make your monitoring effective as possible.

You can also get a profile of CPU usage: Analyzing Query Performance using a Navicat Monitor You'll then get is a list where exactly how much time was spent during the query: or whatever number is assigned to your query. Choose which query to examine with the statement: You'll then see a list of queries the profiler has statistics for.You can use query profiling to measure query execution time. Results are displayed in an easy-to-read grid format: Query Profiling

In Navicat for MySQL, there's a button in the SQL Editor that runs EXPLAIN for me. It takes a bit of practice to get accustomed to EXPLAIN's output, but the more you do it, the better you'll get understanding where your queries need tweaking. You can use this information to analyze and troubleshoot the query.īy default, EXPLAIN output represents the query plan as a hierarchy whereby each level represents a single database operation that the optimizer defines to execute the query. It returns a formatted description of the query optimizer's execution plan for the specified statement. The EXPLAIN CommandĪ good way to see what a query needs in order to perform better is to use the EXPLAIN command. In today's blog, we'll take a look at some techniques for making your queries maximally performant in MySQL 8. Needless to say, achieving sub-second response times takes some doing beyond defining indexes on searchable fields. In many cases, this means measuring query turn-around in hundreds of a second, as opposed to seconds. For that reason, it is imperative that you whittle down your query response time to the lowest feasible value. This in turn degrades the user experience and sours their opinion of your application. Any lagging of the back-end processes will be perceived by the user as a slow or even a non-responsive application. Achieving Lightning Fast Query Response Time in MySQL 8 by Robert Gravelleīehind the slick User Interface (UI) of modern web applications, there are asynchronous services fetching data from the database with a multitude of objectives, including loading drop-downs, populating data tables, Synchronizing components, and many others.
