The workload requirement for a Web server running in Micro-Partitioned p5-550 has increased 300 percent over the past six months. The initial partition definitions assigned 0.5 processing units and one virtual processor to the Web server partition. Three months previously， an additional 0.5 CPU was added to the Web server partition. When the technical specialist attempted to allocate a further 0.5 CPU to this partition， no additional performance was achieved.
Which of the following actions would most likely resolve the problem？（）

A.Add another virtual Ethernet.
B.Change the partition to be uncapped.
C.Change the number of virtual processors to 2.
D.Increase the amount of memory assigned to the partition by 300 percent.
