Re: Poor video performance

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I currently use centos 7 and Fedora 21 guests with gnome3 desktop.

The application I am having issues with is any application that requires redraw on screen (firefox, chrome, youtube, hulu..etc)  I wanted to be able to test apps like arcgis desktop.

Right now I was just expecting quality video streams without the redraw (choppy) issue.

Network configuration is all 10Gbe (internal infrastructure ), but 1gbe for streaming to our laptops

Hi,
I think you should not recompile. I assume you installed successfully QXL drivers in any guest.

However some more details are needed.
- which type of guests are you using?
- with which application type you have poor performances?
- do you measure performance or just expect more responsiveness?
- does screen refresh slowly?
- what's the network configuration?
- what's latency? (like ping response)
- what's the bandwidth? (which kind of connection)

Subject: Poor video performance

Hello,

I am new to using the spice client, and I wanted to know if there is something I can do about video performance.

I am currently using the downloaded version of the Windows and CentOS client (the latest version on spice website)...should I compile the spice client?

My problem comes in when I simulate user experience with youtube, or any application that redraws.  Performance for Desktop applications  (libre, vim, surfing the web..except website with lots of advertising).

I looked at the FAQ about poor performance and didn't know how to check for the options: http://www.spice-space.org/page/FAQ

Any help would be appreciated.  Also, I am using ovirt 3.5.
