Performance optimisations on Photon Bolt

I'm using Photon Bolt latest version and was looking at improving performace and came across this link:

and it mentioned to Call Service Regularly:

To trigger sending any data, a main loop must call LoadBalancingClient.Service() or PhotonPeer.SendOutgoingCommands() frequently

So wondering if this is still relevant for Photon Bolt? Or if it was more for PUN?
