This one is confusing me. When I am watching recorded TV, I typically use the 'skip' function to jump through commercials 30 seconds at a time (in other words, I use the right arrow button on my remote, and each press moves me forward 30 seconds).
This works just fine. But a while ago on my upstairs Client, I noticed that the skip ahead started getting slower...by this, I mean, when I press the skip button once, it skips ahead right away, but it takes a second or 2 to start playing the video again. In the past, it would restart the video almost immediately. I just assumed at the time that it was because I was changed it to a 4k display, and was using MadVR.
Recently, on my downstairs client, the same thing happened, and I realized that it wasn't due to the 4k, it was because I had a small switch daisy chained to my core switch in my closet. My topology is Router is connected to a 16 port switch, and at each TV, I have a 4 port switch that is connected at gig speeds to the 16 port switch. The client is connected to the 4 port switch. The server is connected direct to the 16 port switch. All connections are gigabit. Currently, the only other things plugged into the 4 port switch is the TV, which only takes significant bandwidth if I am watching netflix.
I can put a graphic together if it would help.
So today, I did some basic troubleshooting, and discovered that communication between the server and client is still very fast. I pinged with a large 1400 byte packet (I don't do jumbo frames), and this was my results:

Ping statistics for 192.168.0.120:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms
So communication is not slow, even going through 2 switches.
Anyone have any idea what might be causing this?
