The following characteristics were identified during an early product risk-assessment for a software system:
• the software system needs to manage synchronization between various processes
• microcontrollers will be used that will limit product performance
• the hardware that will be used will make use of timeslots
• the number of tasks supported in parallel by the software system is large and are often highly complex.
Based on the information provided, which of the following non-functional test types is MOST appropriate to be performed?
