Set to a very low limit (e.g. 1), with burst set to same as the limit. Observe that Kueue is making more than 1 call per second to the API Server.
@gabesaba How many calls do you observe?

it should be on the O(#API types). I didn't check if this was multiplied by namespaces, for namespaced types. So in the case of 1qps, at least CQ, LQ, Workload, Pod, Event (and others I may be missing) = 5qps.

How do you "mesure" this?

I'm not sure what development environment you're using, but generally:
- access k8 apiserver logs
- filter requests from Kueue
- add some load to Kueue so that it's making enough API calls
- group by time observe that in a given window (e.g. 60 seconds), there are more than 60 calls (if qps=1)
- additionally, group by API type (Workload/Pod/CQ) - observe that qps is at most the limit you set

@gabesaba It took some time but I found the cause, #2462 should fix it, please let me know if you can confirm the fix on your side as well.
