One way to know that a company or business is performing well in the digital sense is by measuring the performance of applications. Application performance is measured to check whether the user needed to wait longer than the required amount of time to get what they want. Metrics for application performance vary under different scenarios. For example, a HR page may be allowed to take a few seconds longer to respond than a mobile shopping app. Every business needs to enhance MySQL performance for efficiency. Research shows that performance impacts user behavior in various ways. Some of the findings from the research carried out include: When a website takes longer than 3 seconds to load, 40% of the users tend to abandon it. When a website is slow, 79% of customers are less likely not to return to the site again. More than 45% of consumers expect a webpage to load in less than two seconds. A delay in page load time can lead to 11% fewer page views and a 7% loss in conversion. As you can see, it is vital to maintain good application performance. When the application performance is poor, you not only stand to lose money but you will most likely lose business to competitors with better application performance. One of the main factors that affect application performance is database performance. The interaction between databases, websites and applications is very critical to establishing the recommended level of application performance. MySQL is by far one of the most popular database management systems and more and more businesses are shifting to finding better database solution. There are several methods of configuring MySQL to help your database respond in less time. These tips will help you optimize your MySQL database performance: Create the Right Indexes Database indexes are more like book indexes and they contain information that is found in the main database. These indexes are kept in their own location and used as a reference map to locate data. Check your database index to ensure that not even one index is missing. When an index is missing, it can bring a database to a crawl. You can remove indexes you don’t need as unnecessary indexes make databases slow down. Avoid Defaults MySQL has configurable settings that are used to modify behavior which affects performance. Just like any other software, to get a better performance, it is vital to understand MySQL configurable settings to allow you to set them work best for your database environment. It is unfortunate that most administrators end up ignoring these configurable settings and they end up being used in their default mode. Keep the Database In-Memory Recently, the transition from spinning hard drives to solid state drives has made it easy and faster to access stored data. However, even SSDs are still no match for having available data in RAM. Whether you are managing your own hardware or running data in the cloud, it is possible to get your data in memory. All you have to do is fit the data that you access most frequently into the memory to get in-memory performance benefits.
