Hello,

Describe the bug

We have a big kubernetes cluster with almost 3000 argocd applications.
Currently we are running ArgoCD 2.2.2.
Since upgrade to version 2 we noticed that refresh of the resource tree for applications is much slower. For example:
I click on "Restart" for a deployment
ReplicaSet appears immediately
New pod appears sometimes after 40 seconds
I've tried increasing values --status-processors, --operation-processors, --kubectl-parallelism-limit for the controller, but it does not help.
Any idea what could we do? Which component is responsible for this refresh, is it argocd-server?

To Reproduce

I click on "Restart" for a deployment
ReplicaSet appears immediately
New pod appears sometimes after 40 seconds

Expected behavior

Pods should appear faster.
