Job execution 
Command execution is not tied to a fixed cycle and depends on the number of 
busy commands and on CPU load. The maximum and average task execution time 
can be read from the CmdLoopDuration and MaxLoopDuration variable of the 
MCDevice technology DB. 
In order to tune utilization of system resources, you can reassign the technology 
objects a new command execution cycle. Assign the high-priority technology 
objects a shorter, and the low-priority technology objects a longer cycle. 
For information on how to reassign the execution cycles of technology objects, 
refer to the chapter "Assigning technology system cycles". How to set the cycle 
lengths is described in chapter "Tuning technology system cycles ".
