Hi everybody

1.I divide my desktop(2 processors ,2G memory) into two VMs(each entirely owns 1 processor ,1G memory).Then I run two tasks simultaneously(task0,task1, they are independent to each other) on these two VMS,the time consumed is T0;

2.I run the same two tasks simultaneously straightly on the desktop,and the time consumed is T1.

I found that T1 is always 2 times as T0.Is this result common or is there any papers(reports) illustrates this kind of question?

many thanks
