In the Windows Guest, I saw the usage always is 100% and I had assigned 16GB ram but in VCenter Performance, I saw the Guest is VM performance using memory around 10% only and the active memory is less than 5G so Why have the different?

Sorry, I am new to vmware,  I read some vmware document, But I want to know the memory resource control? If the memory overcommit, the esx will do page sharing, balloon and finally swapping. But the memory overcommit mean all vm guest assigned memory ? vm guest active using memory? Our VDI host have 150GB physical ram(VM assigned around 260GB ram), The physical memory usage is around 80%, but we saw many page share and balloon in the performance tab,  I think is not enough memory so incur balloon and swap to make the vm guest performance poor. But my boss think "Memory overcommit" is mean sum of all vm guest active memory. we didnt set the memory reserve. I am going to propose, set each vm guest ram (win 7 64 bit) and reserve 2Gb ram. Currently most of them set 8GB ram but didnt setup any reserve, in the vm guest usage, i dont see many memory usage, so i think reduce the each vm memory and do the reserve will make all performance is better
