Hi Everyone,

 

The time has come for me to build out a new HTPC, as my trusty Thermaltake DH101 has outlived it's usefulness (the VHD display went bad, plus all of the lights on the front where getting annoying).

 

I'm seriously considering building out a server that will act as a central repository for all of my media and a tiny mITX box acting as my HTPC.

 

Both would be connected via 1GB Ethernet.

 

Playback of the media would be thru Media Browser 3 Classic, being served by Media Browser Server (MB3 Server would be installed on the server).

 

Pretty straightforward stuff, a lot of people on this forum probably have very similar setups like this already.

 

Here's the question: Playback of high bitrate content via 1GB - anyone notice laggy seeking, dropped frames, stuff like that?

 

Thanks!

Gigabit: 1000 mb/s
Blu-ray: max bit rate ~40 mb/s

You will not have any issues streaming video over gigabit ethernet.

Max bitrate for bluray is 55mbps if I recall so there will be no lag issues, especially if you are playing dxva files. If anything, you might notice latency issues depending on how you are set up.

yea, it just is simple math.
100 megabit is more than enough for bluray, which is 40 megabit tops iirc.

If you are talking about stuff you encoded from a camcorder, then it depends on the bitrate, but I can't imagine you using close to 1 gigabit bandwidth.

Thanks much Lockdown, DotJun, Mindbomb, your advice makes total sense.

 

I performed some testing this morning to help satiate my curiosity:

 

Test Beds

 

1) Installed MB3 Server on an old desktop (Phenom II x4, 8 GB DDR3 1333 RAM, two 1 TB WDD HDDs)

 

2) Copied up 5 different folders containing MKVs of varying bitrates (all where pretty high, pretty large rips) and their metadata and stuff

 

3) Uninstalled MB2.x and installed MB3 Classic on my current HTPC (LAV Splitter, LAV Video, LAV Audio, EVR)

 

4) Played back content thru MB3 Classic, streaming from MB3 Server, 1 GB Ethernet between both systems

 

Streaming Test 1: Results of Streaming Video vs Local Playback

 

1) Picture quality - Good, streaming versus local no difference

 

2) Seeking (FWD/RR) - Good, streaming versus local, no difference

 

Test 2: Results of Streaming Video vs Local Playback - Heavy Disk I/O on the Server

 

For this test, I started copying 30 GB of data between both WD Green HDDs on the server.

 

Disk I/O hovered about 60 MB/sec

 

CPU usage was nil

 

1) Picture quality - Good, streaming versus local no difference

 

2) Seeking (FWD/RR) - Not good, streams kinda froze up a bit, sometimes got to the point of being unwatchable

 

Final Thoughts

 

As I am heavily dependent on seeking forward and backwards, I'll need to build out a Media Server with a good disk subsystem. I'm thinking WD Reds (maybe Greens) in a RAID array.

 

I know, it sounds weird that I care so much about seeking, but I have a habit of falling asleep while watching stuff and need to seek to the point I left off. Also, I like to watch scenes two, sometimes three times in a row to make sure I get all of the dialogue and take in the settings, etc.
