Improving OpsCenter Master reconnection ?

Looking for ways to improve OpsCenter reconnection to Master servers, it often takes long from a Master Server is pingable from the OpsCenter server to the Master has status Connected in OpsCenter.

Have increased the database cache and number of CPUs, the next thing will be increasing the OpsCenter Server Service heap.

Have looked at the OpsCenter Performance tuning guide, but thinking there might also be some OS settings there could improve the reconnection.
