Current Behavior

After changing cluster groups using (containing different set of clusters) in GitRepo, taking too much time to remove resource from cluster. I observed it took more than 2-3 mins.

Expected Behavior

Application or resource should be removed within few seconds and should not take much time to remove it.

Steps To Reproduce

1. Add same labels to the cluster-A and Cluster-B
2. Create a cluster group of cluster-A and cluster-B using same label.
3. Create a GitRepo and in Deploy To section select cluster group name.
4. Wait for resources created on both clusters.
5. For Third cluster-C, add new label to it.
6. Create another cluster group of third cluster-C using new label (added on cluster-C)
7. Update GitRepo with newly created cluster group.
8. Wait for the application to be create on third cluster-C.

Does this happen if you only create cluster group A and not a second one B targeting the same label?
