    Probably none. Another option is a little.

    Depends. For a usual day to day use case it would be a wonder to even need any.

    I have a heavily modded Skyrim rig. I have 16GB of ram. They suggested I create a 20GB swap. But they said if I had 32GB for ram I wouldn't need any swap. This is in windows though. Not sure if you need any in Linux.

    32gb cause codebase has too many memory leaks

    @h3rp1d3v report them to get them fixed.

    Saves it for other people. Also makes the software more stable and faster.

    Doesn't hibernation use swap? So i guess you need at least 32G?

    Got quite confused about all this not long ago, too.

    @nitwhiz swap is extended RAM, hybernate is snapshot of RAM for restore later on.

    @nitwhiz @max19931 but it uses the swap. If you have an encrypted partition you have to also encrypt the swap or you have a password leak.
    i usually encrypt the drive woth luks and put an lvm pv into it.

    swap=0

    if you'll be using hibernation: swap+=32GB

    If you're planning on leaking memory / using up all the 32GB of ram -- swap+=estimated_leak_size

    You'll need ${swap} of swap

    @nitwhiz yeah, you need either a swap file or a partition. If you want to avoid extending memory with swap but want to use hibernation, you could try setting vm.swappiness to 0.
