Depending on the amount of data, deleting an OSD can be a slow operation. We do not have found a really slow behavior deleting osds but our environment probably does not have the same amount of data that QE is using. Please retest, using the command to read the deletion status, and provide more information about load. Please attach the mgr log if you see the slow behavior
Same delay using the --force parameter? try: # ceph orch ls --refresh
