@kzcPo Could you provide steps to reproduce? How many rollouts Manifest for rollout

I run a command kubectl argo rollouts dashboard.
My program calls API every 10s. /api/v1/rollouts/online/info
Through dashboash, you can see that the response time of this interface is 3S.
At this time, the pod CPU continues to grow until the OOM kill.

It also takes 3S to execute by command.

Is there an API server that can be provided for my program calls？ Can this query be optimized for time consumption？
