Sure, cilium is also much faster than istio. But I guess it depends on your workload. We don't care all that much about performance vs compliance (non-hft finance transactional stuff) and I think we're doing things reasonably well. :}

I didn't mean replace istio with cilium, I meant running the proxy and routing operations as shared part per node instead of per pod

How does that even work with envoy? The magic sauce behind istio is that every connection is terminated using iptables into the envoy process (sidecar), and istiod spaffs envoy configurations around the place based on your vs/dr/pas/access controls etc.

I suppose you could have a giant envoy and have all the proxy-configs all mashed together but I really don't see any benefit to it? I can't even find documentation that says it's possible..
