Laggy slow transcoding server

[flokicat 0]

Hi i have recently changed my my primary emby server... from i3 2120t (2c)  and 4gb ram to dual xeon X5660 (24core)  with 31 gb ram and my performance is so slow that i3 culd run 4 1080 streams at once no problem and you culd scrub as much as you wanted it was almost instant .... new machine  won't get to more than 2 % on cpu and it takes 15-20 seconds to load from a random timeline.... idk what to do... i have tried updating that didn't help at all so yeah i am staying on ver 4.5.4 ... oh and i am premire user.

I know that gpu culd fix that in an istance but all of them are in use. (don't ask why

off topic if someone knows where in code to enable backdrops for all users pls let me know

thanks in advance

Please wait for someone from staff support or our members to reply to you.

It's recommended to provide more info, as it explain in this thread:

Thank you.

Hi there, let's look at an example. Please attach the information requested in how to report a problem. thanks !

The odds are the i3 will have quick sync (graphics) and the Xeon will not, so no hardware acceleration at all for Xeon.  But yes specific examples with server/ffmpeg logs.

Also staying on older versions (4.5.4.0) will prevent us from properly troubleshooting issues.

@flokicat This is exactly whats happening. Intel I Series have i-GPU and Xeon don't so you are just using software transcoding.

A screenshot of your server dashboard while having a transcoding stream will prove that. You will see "Software" but no "hardware accelerated"

Now, your ONLY solution is to use a GPU, if you wanna keep your new Server.

Yep - the i3 was one of the very first intel cpu's to include Quicksync - look half way down this page.

In contrast - the Xeon X5660 does not - and frankly is a 10-11 year old cpu, that is going to be extremly power hungry (120W/Dual=240W!).

A very cheap modern Pentium Gold or i3 is going to run rings around the Xeon for transcoding, plus it will use a fraction of the power doing it ..

Time for an upgrade (or keep using the existing i3?)

you did a serious step backwards going to Westmere.  Just because you have more cores doesn't mean you have more processing power.  Sell your server and upgrade to something from Intel with integrated graphics.  Look for at least Coffee Lake or higher for HEVC encode and decode in hardware.  Heck even just using a modern laptop as your encode box (with all media stored elsewhere) would suffice and get you at least 20 1080p encodes without breaking a sweat.

Have to agree with others.  For a media server you went backwards in performance where it counts by removing the integrated GPU.

If using existing GPUs for mining you should check your real earnings (what you have received) minus electric costs, minus cost of equipment (amortized) to find your true profit if there is any (might be surprised). When I factor these things vs having my different hardware tied up and being "burned up" needing replacement much sooner it clearly isn't worth it especially when I can repurpose that equipment for other things that add quality to my life.

Example using a GPU for Emby.

If that's not what you're doing then of course ignore that. LOL

Depending on the amount of storage you have and plan on having you may want to use the current XEON machine for storage and not for Emby. If you switched your OS from Windows server to a Linux distro you could easily run a lot of docker instances on the storage server to gain a lot more services and apps for your home lab. Being able to run a bunch of small apps like this would help justify the cost of electricity those old XEONS use.
