64Gb: Is SWAP still needed?

Going to setup another Qubes machine with 64Gb and I’ve checked memory usage on my other machines and ~60Gb is as high as I’ve seen when trying to max memory out (~30Gb is the normally high figure). With that said, is SWAP needed or can I safely remove during R4.2.1 install?

Swap partition that you add during installation is only used by dom0. By default dom0 have 4 GB of RAM and it could be not enough in some cases so it’s better to have some swap.

Thanks for the quick response. I’ll keep it. I noted this good reference too.
