Which gives better performance: WCF RIA services or Domain Services?

I am building a new SV application which will be used from the Internet. I am expecting to
have a few users at a time, so I will need good performance.
Which is better to use:
build from 0 WCF RIA services or
use Domain Services?
On WCF RIA I can set up a service behavior for ConcurrencyMode but for Domain Service I couldn't find any info about that.
Also I am a little new to this so be gentle :).

wcf service start

I have a wcf service inside a windows service. Inside the wcf service I have a http listener which needs to be started automatically when the windows service is started. Any ideas?
Thanks for the answers but I found the solution
In order to have your constructor called, you need this:
[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Single)]
can you not use IIS to host the WCF service, it has the WAS (Windows Activation Service ) to start the WCF Service?
