Re: [Xen-users] To Xen or not to Xen

["François Levasseur" <francois.levasseur@xxxxxxxxx>]

Ok I already have a memcached server, a static server (lighttpd), and a database server. I also have a load balancing server to distribute http requests.

I have an opteron that is already fill up with dynamic http request (php, apache2-prefork). So I bought a new one, with 2 cpus dual core.

I wonder if I'll get more performance with Xen and two or four domUs? If so, why?

Frank,

I'd say use Xen and create a guest for each core. I'm not sure what
kind of web serving you're doing (dynamic or otherwise), but it would
take a lot to fill up ONE Opteron, much less two. You'll max out the
bandwidth first.

With this in mind, I'd suggest creating the following domUs:

one guest, dynamically generate a cache of static pages (assign two
cores)
two guests, each serving those static web pages, setup in round robin
fashion via DNS (one core each)
