I requested this a few months ago as my server was sitting unused and I wanted to help. Never got an answer back, maybe because the server's specs aren't great. Either way now I've got nextcloud running so unfortunately too late :(
You probably had the "laptop mode" toggled on in the setup. With it on you will rarely get games to analyse. This will only send you games when the network is stressed. If you toggle it off you should get one game after another almost constantly.
I doubt it's speed. I was getting constant games with an i3-5100.
