What server/hardware parameters affect skip performance?

Channels DVR Server
#1

I'm looking for any performance tips to speed up seek and skip (in both directions) of content recorded from a Silicon Dust network tuner.

I'm not having any real issues -- I'd just like to speed up skip/seek.

Environment is the server runs on Proxmox and streams to an Apple TV 4K (1st gen).

It seems to me that an earlier version used to perform skip/seek faster, though I have no data to support that assertion. The only other difference, I believe, is that the library has grown larger (it's on a wired connection to a Synology NAS; that device's utilization doesn't move either the network or disk throughput needles).

Suggestions appreciated.

Networking. That’s pretty much it.

Use Ethernet with a gigabit connection to your streaming device. If you can’t run Ethernet, investigate MOCa adapters to bridge your network over existing coax, it’s great.

The other issue could be an old slow spinning disk drive that’s being over utilized while you’re watching. But it’d have to be real bad.

Also, make sure you’re using Original for your Streaming Quality and aren’t transcoding.

Since your CDVR server and file storage are separate, you might find some benefit from moving to 10Gbps connections wherever possible -- or at least 2.5Gbps. Both can be done over standard Ethernet cables at various max distances (Cat 6a or better).

I moved to Proxmox last year (which has been beyond fabulous), and upgraded as much of my wired infrastructure as possible at the same time. Moving multi-gigabyte video files now happens in seconds.

I use the built-in gigabit port on my Proxmox server for admin and Wake-on-LAN, and the 10GbE port for everything else. Revealed when my rural provider suddenly started supporting 2Gbps too. :slight_smile: Amazing stuff when you're 50 miles from anywhere.

Thanks.

I'm prepping for a move and as part of setting up the network there, I'm installing a Ubiquiti-based network that connects to a 10Gb switch.

The ISP in the area offers 5Gb service over fiber, so I am really looking forward to having (for the first time) a network on my side of the ONT that can outpace the ISP. Though that doesn't make a real difference in this application, I'm hoping the overall increase in capacity has a trickle-down effect on Channels.

If you haven't bought your equipment yet, you may want to look into Omada. UI has been on a slow decline as of late (IMHO) and if you haven't purchased your hardware, check out other options to be sure you want to go that route.

I have all UI and I have 0 complaints.

As do I, at 3 separate locations. I was simply stating my opinion regarding the current state of UI; also that Omada has near feature-parity, and seems to not have as many edge case issues.

Also, UI stock/supply seems to be perpetually low or out.

I have UI and Omada at various places. I lean towards Omada, but only because of price. I was certified with Cisco using the CLI, so both of them (Omada and UI) seemed a bit clunky to me in the beginning, but they have grown on me over the last few ars.
