Investigation into CPU utilization when streaming

[camping147 0]

Hi,

 

I have noticed (especially since the Android client came out THANKS!!) that CPU utilization goes up on greatly when streaming from either a web browser or the android client (both remote and local) .  How many concurrent streams can MB server do before shuttering?  Even though the CPU % goes to 100% in task manager I noticed I can at least do two concurrent HD streams without much shuttering.  How many can MB do?  I would guess it depends on the setup but does it use any of the new extensions/Intel Quick Sync from the newest CPU's? I assume using MBC and MBT the rendering is done on the client side whereas in a browser/android side the rendering is done on the server side?  My specs

 

Server 2012

Core i5 2500K

16 GB ram

Two raid arrays with content

boot drive is an SSD

 

I also have two VM's in hyper v running

one is a Ubuntu server doing SSH for my network (MB and android client works great through SSH tunnel)

one is windows home server 2011 (used for network backups)

 

Is there anyway to lower the CPU %?  When it gets pegged near 100 it uses a lot of power and generates heat, which could affect the HDDs long term.  Or is it worth it upgrading to the newest Intel CPUs to lower CPU use? 

 

PS probably going to upgrade to server 2012 R2 soon.  I assume MB works with that as well right?

 

Keep up the great work!!!

When streaming to any of the apps (android, ios, wp8, etc) the server is transcoding the video on the fly for the app to play.

I'm running an older dual cpu setup for two 6-core 1.6 opterons, I tested yesterday to do 5 streams (granted not all at HQ, 1 was 8mbp via roku, 2 of the others were less than 1mpb because I was doing them from a phone, and 2 via web browser at 480p setting.

It seems to depend on the source of the content you're playing. I can do 2x blue ray rips with DTS (25gb file) and two 720p/1080p mkv/mp4 (2-4gb files) from the browser before I see my CPU spike to 100% Core i7 2600k, 12gb ram. and sata III SSD. 

 

We'll need lots of processing power as RAM doesn't do much for us here. I never saw more than 30% of my ram being used.

Would like to know as well if MBS can use hardware acceleration via quick sync or dxva as in MBT for help with transcoding and if so are there any settings that need to be set or is it automatic.
