[Xen-devel] Xen guest performance as a streaming server
Hi,
I am using xen3.4.1 with pv kernel 2.6.31.4 and testing my xen
guest performance as a streaming media server and the other as web server. the
trends are same for both of them.
(1)When i tried to access media files from an internel guest, streaming looks
very poor.
(2)Then incase of accessing them from an externel guest its again poor but just
a little bit better than before.
(3)Incase of accessing them from host of the same machine it results good.
But i have not such issues with my previouse set up on FC8. Why the guests acts
like this?
Regards,
Fasiha Ashraf

Yes, get the latest pv-ops dom0 kernel 2.6.31.5. I have just installed it. I think FC8 Xen is not based on pv-ops but on conventional Xen linux 2.6.18 forward ported. -- Mr. Teo En Ming (Zhang Enming) Dip(Mechatronics) BEng(Hons)(Mechanical Engineering) Alma Maters: (1) Singapore Polytechnic (2) National University of Singapore My Primary Blog: http://teo-en-ming-aka-zhang-enming.blogspot.com My Secondary Blog: http://enmingteo.wordpress.com My Youtube videos: http://www.youtube.com/user/enmingteo Email: space.time.universe@gmail.com MSN: teoenming@hotmail.com Mobile Phone (SingTel): +65-9648-9798 Mobile Phone (Starhub Prepaid): +65-8369-2618 Age: 31 (as at 30 Oct 2009) Height: 1.78 meters Race: Chinese Dialect: Hokkien Street: Bedok Reservoir Road Country: Singapore On Mon, Nov 2, 2009 at 6:41 PM, Pasi Kärkkäinen <pasik@iki.fi> wrote:> On Mon, Nov 02, 2009 at 02:36:27PM +0530, Fasiha Ashraf wrote: > > Hi, > > I am using xen3.4.1 with pv kernel 2.6.31.4 and testing my xen > > guest performance as a streaming media server and the other as web > server. > > the trends are same for both of them. > > (1)When i tried to access media files from an internel guest, > streaming > > looks very poor. > > (2)Then incase of accessing them from an externel guest its again poor > but > > just a little bit better than before. > > (3)Incase of accessing them from host of the same machine it results > good. > > But i have not such issues with my previouse set up on FC8.
