How to Improve MySQL Performance with Memory
Virtualized MySQL databases handle most of the world's data and online transaction processing, yet they're often underutilized and prone to spikes and erratic workload performance, which costs organizations a significant amount of time and money. When database responsiveness is on again/off again, you aren't able to get a consistent quality of service that can fuel exponential data growth. However, because quality of service revolves around active data rather than the number of virtual machines (as is often thought), the MySQL performamnce variance problem can be easily solved by maximizing server memory footprint.
No matter what you're using MySQL to do, more memory enables more transactions per second, more consistent quality of service, and reduced acquisition and licensing costs. Don't just take our word for it, though. Duplicate the test below, experience the difference, and start getting more out of your IT budget.
As the test below shows, increasing the amount of memory in the server results in more transactions per second and a lower mean response time.
