I don't think that's something we've ever tuned for or benchmarked against, but yeah I would expect it to be the same as upstream.

Haha I figured. I don’t think it’s something most folks think about until it becomes a problem. 🙂 Thanks!

We’re into the low thousands of CRDs in Crossplane so we’re seeing API server memory usage climbing above 5GBs.

Interestingly https://github.com/kcp-dev/kcp seems to be the best in this regard - they’re at something like 1-2MiB/CRD. I thought that might be because they’re lacking a bunch of OpenAPI functionality, but if I understand correctly k3s dropped some of that too.
