How much ram is needed to use --index-sats?

[Michaelmint]

I am trying to index with sats however I am hitting the memory limit of system. I am working on testnet (Could that be the issue?). I have 16gb of ram on my system and for the first 500,000 it sits at around 2gb of usage, then it crash's at 790,000 due to me hitting my OOM. I saw a some info about needing at least 64 gb, but I am unsure if that is correct for the modern ord. Info on this would be great.

On mainnet you need at least 64gb. you can also play around with the --index-cache-size and --commit-interval flags and see what works for your system. Do ord help for more infos
