I've installed Debian with the default values:NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT

31,8G of SWAP. Holy fucking shit! Why?
your amount of ram times two

How much RAM does your machine have? I bet you have at least 16GBs.

>>54413443
if you have 16GB of memory then 32 GB of swap is the "recommended" amount as in "won't collide with anything" amount

That's exactly it. I never use all the RAM. I think I'll never use those 31,8GB.
>>54414024
Then same as you shouldn't have all this RAM if you'll never use it, you shouldn't have all this SWAP if you'll never use it.
What is swap?

But you can always remove/shrink that partition and, as an example, adjust the root partition to fill the void

Swap is useless, it was good back when people had 1GB of ram available, today there is no reason to have swap at all. Delete partition, grow sda2 and delete swap entry from fstab. It's literally wasted 31GB

Well hibernation would be one good reason to have that much swap. The defaults seem to err on the max side of swap, which is 2X ram.
If you don't use hibernation, 4GB can be considered a sane default regardless of ram size.
>>54414217
That doesn't sound right

Well I'd say at 16GB point swap becomes somewhat useless, before that there are clear benefits.
Unused pages can be stored in swap and thus free up more memory.
More memory means bigger cache to store files for fast fetching.
I can easily populate 16GB ram in normal work scenarios, it would suck balls if I didn't have a swap file.
