PixelStreaming FPS drops

Hello developers,

i have been playing around with Pixel Streaming and have a problem with performance on the client browser. Moving through the level and especially moving the camera produces very harsh fps drops. I have tried to connect to the Signaling and Web-Server through LAN and the Internet. Its worse throught the internet, but still happens in LAN.

What are possible things I could look at, or is it purely connection related ?

Thanks!
