Peter, Tricky. Is it running in its own address space, or is there other work going on in the address space at the same time.
If running in its own address space - TSO RMFWDM will give you near real time reasons for delays, CPU, which volids If other work in the same address space - do you get any stats out? If the address space is lightly loaded with little work - then the transaction could be delayed 10's of milliseconds and you would not notice. If another transaction is running which uses lots of CPU, or lots of IO, or does a database query (involving a lock). This would cause your transaction to be delayed. For example 1000 IOs at 1ms per IO is 1 second of wait. TSO RMFWDM is a good start to see what the address space is belong delayed for.
