Hey all 👋
Probably a tough question to answer, but here goes....
I have a Rancher instance on 1-node k3s that manages some 35 other 1-node k3s downstream clusters, which works fine. However i have this nagging feeling that my Rancher instance uses more memory than it should for it's size, typically it uses 3-4.5GB of memory per replica which seems high when according to the docs 16GB should be enough for an instance that manages 150+ clusters
https://ranchermanager.docs.rancher.com/v2.7/getting-started/installation-and-upgrade/installation-requirements#hardware-requirements
My rancher instance is quite old (4years+) and has over the years seen many clusters come and go so i suspect there is alot of "junk" that could be cleaned up.
Any input on this? Is my memory usage normal? If not how can i identify what's casusing the high usage?
Thanks 🙏
