If you want to test with load, then you won't get it in the staging area 
but only in the production area. ;-)

So, yes we have a staging area but this won't help here.

I'm sure it's possible but as I wrote in a previous mail, the service is 
currently working with only one mirror URL at the same time. So, we have 
to change this first before we can balance the load.
