Title: FPP - Data sending VERY slow to Controllers after 12,429 channels selected
Post by: derektoews on October 14, 2017, 10:03:56 AM
So, I've done my fair share of research on existing forums regarding this matter and I've tried multiple things to resolve this... I'll explain more, but the issue is that the .fseq data is sending very slow to Controllers... I have switched out jump drives (4 different ones), switched out micro SD's (3 different), reinstalled FPP...

Playing directly out of Xlights, plays perfectly fine.
When I play out of FPP, and I only select the first 12,429 channels or 27 universes, it plays perfect, no lag. (This is also my only my first 4 controllers) If I select the next universe, (which is the first universe on my 5th controller) it starts to lag, a lot. The more universes selected, the more it lags to the point where it's like the lights will change every two minutes, literally. My total channel count is only 18,978. I'm running FPP on a Raspberry PI 2 B. I'm running version 1.9, the latest. Everything is run Unicast, I don't actually have all the controllers hooked up, just 2 of them into the network at the moment. Controllers are all Sandevices, e6804 (3) and e682 (2), updated to V5 firmware. Just trying to give as much detail as possible as to if it matters. From forums I've read, these Raspberry PI's should be able to handle 128 universes + so I'm a little confused as to what is going on here...

Is there something corrupt in the Xlights .fseq files? I have regenerated the .fseq files out of Xlights and uploaded 2 different versions to FPP and same thing happens.

If you are running unicast all configured controllers MUST be online.

Gotcha. I actually only had to hook up the 5th controller and then it was playing normal. I wonder why that is... either way, I really appreciate it the info! You live and you learn.

It has to do with network acknowledgements and if a controller is not online it waits for a timeout to occur.  This is a common and well known issue.

xLights on your PC gets away with it because the network controller is MUCH faster than the USB driven network controller on the Pi.

You guys are really smart. I don't know how you know some of this stuff. At some point hopefully I'll learn everything.

We are not any smarter than anyone else, but we are experienced and have been doing this for a lot of years.  We also read almost every post to continue learning.
