[ClusterLabs] Pacemaker serializes start operations

I have a dependency tree starting with PgsqlShared as root, and two sub trees:
With the version on Pacemaker that came with SLES11, the starting was done in parallel, such as
2. apache and iproute - parallel, as expected
With the version of Pacemaker that comes with SLES12, the starting is serial:
5. iproute - delayed until the first sub tree completes
I have searched for solutions and found a number of variables that should affect this area. I tried to set all of them in different combinations, to no effect.

20:18:45 root at BC-H1008-spb spb:~> echo $PCMK_MAX_CHILDREN
20:05:56 root at BC-H1008-spb spb:~> crm_attribute -Q --name batch-limit
20:06:01 root at BC-H1008-spb spb:~> crm_attribute -Q --type nodes --node spb --name node-action-limit
20:06:28 root at BC-H1008-spb spb:~> crm_attribute -Q --name migration-limit
Any pointers appreciated.
