- __turbobrew__ 11mo agoWhen I was involved about a year ago, cilium falls apart at around a few thousand nodes. One of the main issues of cilium is that the bpf maps scale with the number of nodes/pods in the cluster, so you get exponential memory growth as you add more nodes with the cilium agent on them. https://docs.cilium.io/en/stable/operations/performance/scalability/report/ https://docs.cilium.io/en/stable/operations/performance/scal...
- oasisaimlessly 11mo agoWouldn't that be quadratic rather than exponential?
- preisschild 11mo agoThats true and I definitely had to "tune" the bpf map limits, but it wasn't really that difficult to do.
