Stakepool min requirements

[TooCoolName]

I do not get this from this url: https://developers.cardano.org/docs/operate-a-stake-pool/hardware-requirements/

Servers: 1 for block producer node + at least 2 for relay nodes
Memory: 24GB of RAM

Is memory of 24GB for each server required?

Yes for mainnet.

@TooCoolName I've tested some boundary cases, including less memory, and can personally confirm a minimum of 24GB is currently required for each type of node to operate normally.

24GB RAM will always give a better performance.

Not always, for sure: it would be incidental to other configuration parameters, including the number of CPUs. I've observed perfect performance on a stake pool configuration that has never used more than 13GB on either the block producer or relay nodes.

The difference between this statement here and my last #1268 (comment) above is in finding better GHC environments in the last 2 months. Most of the 24GB I've seen eaten by the nodes has been going into the GHC heap, whose size can be curtailed without limiting performance at all. (cc @gitmachtl)

But for SPOs who don't want to or can't learn how to tune GHC RTS parameters, 24GB RAM in my experience offers good performance in the default configuration.
