Photon Handler.Update framerate

Hi! I noticed that when I use PhotonNetwork.ConnectUsingSettings or createRoom the game is lowering the FPS for abount 2 seconds.
Using the profiler I found it was because of PhotonHandler update (deep profiler shows that the most of the CPU usage is generated via some calls to photon dlls from PhotonHandler update).

Is there any way that I can place this updates inside a thread only in that cases to avoid this decrease of the FPS?
Thanks
