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
