How much should be the value of high water and low water with 512 MB of ram

I have a server with 512 MB of RAM and 1core cpu. I want hightest high water value with this specs. Is there any utilities to help here. Or what’s your assumption by the way.

High: 50
Low: 25
GracePeriod: 10s.

Try that and monitor memory usage.

I’ve taken a similar approach. I have several IPFS nodes running on the same machine (inside Docker containers). I set the High to 50 and the Low to 30, in order to help manage memory and network usage.

I don’t have any data on performance improvement though. I’d love to see some hard numbers on how to reduce memory consumption of a js-ipfs node.
