![]() ![]() Troubleshooting performance issues requires the establishment of a baseline, which will serve to compare to the changes made after it, and evaluate if the overall performance improved or not. leading to lower transactions per second (TPS) due to competition for resources.īeing able to fully understand the problem helps identifying where on the stack a misconfiguration could be leading to reduced performance. This situation leads to more requests flowing back to the origin server, instead of being served by cache.Īnother example would be when the redo log of a MySQL/MariaDB is located on the operating system (OS) disk or on a disk that is not up to the database requirements. An example would be a web application with a caching layer is not correctly configured. There are instances where performance problems could be caused by a misconfiguration of the application/setup. Each of these areas generates different symptoms (sometimes simultaneously) and requires a different diagnosis and solution. Most issues are related to CPU, memory, networking, and input/output (I/O) as key areas where the issue occurs. Performance issues occur in different operating systems or applications, and every issue requires a unique approach to troubleshoot. ![]() In this article Performance issues and bottlenecks ![]()
