B) Often shared hardware is over-allocated resulting in less than expected available capacity (e.g. 2 vCPUs may equate to 0.1 physical cores)
C) It is important to validate the actual performance of the Runtime Resources when operating on shared hardware
D) The performance of the Runtime Resource can impact processing throughput
E) All of the above
