Using the Product in a CICS Environment › Transaction Response Times
Transaction Response Times
CICS transaction response times are affected by these major factors:
- System response time - depends on the implementation of the code and the speed of the processor
- DASD response time - generally responsible for most of the internal processing of a transaction
- Network response time - can be in seconds or the internal time can be a fraction of a second
If the network is overloaded, you will never get good response time
CA Mainframe Application Tuner helps you monitor the internal processing time of a transaction but cannot identify problems with your network
- Existing workload - might affect the performance because of contention for hardware resources or logical resources
- Application design - might affect performance because a task might use excessive resources
