Response time is the number of milliseconds, seconds, minutes, hours, or days that a single task takes to complete. You can improve response times by:
Making queries, transactions, and batches more efficient through query tuning and indexes
Using faster components (for example, faster client and server processors, and faster disks and storage).
Minimizing wait times (for example, by improving network, physical, and logical lock contention)
In some cases, Adaptive Server is automatically optimized to reduce initial response time, that is, the time it takes to return the first row to the user. This is especially useful when a user retrieves several rows with a query and then uses a front-end tool to browse them slowly.
