I have servers running VMWare. The server is a Intel Xeon with 96 Gio of RAM. We need to increase the RAM on the server (assume with the same memory model). Somebody told me adding more memory to a computer can slow it because there's more address space to look after.
I'm pretty sure it's bullshit and I can't find any paper that confirm that adding memory can slow down a computer. Instead, I have only documentation that confirm that it can speed it because it can have a bigger swap.
So my question is : Can adding RAM to a server can make it slower? If so, is it perceptible? Do you have any documentation on the subject?
