What should Connie focus on to troubleshoot the increased response time of her SQL database?

To troubleshoot the increased response time of a SQL database, focusing on storage is crucial. Database performance is heavily influenced by how quickly data can be read from and written to storage. If storage is slow or overloaded, it can lead to significant delays in processing queries, resulting in increased response times.

Various factors related to storage can impact database performance. This includes the type of storage used (e.g., SSDs versus HDDs), the speed at which data can be accessed, the configuration of the storage system, and the overall I/O operations per second (IOPS) that the storage can sustain. For example, if the storage subsystem is not capable of handling the read/write demands of the database, this will directly lead to slower response times, as data retrieval and storage are key operations in database transactions.

While memory, CPU, and networking are also important components of overall database performance, issues related to these areas would typically manifest in different symptoms. Memory problems could lead to increased caching or swapping, CPU issues might cause high load on processes, and networking problems would affect data transmission speeds. However, when specifically dealing with increased response time, storage is a focal point, as it directly correlates with how quickly data can be accessed during query processing.
