For those of us in the US, yes, it's higher.  From Europe I suspect
it's faster for them than it is for us.

Typical responses when hitting app3 and app5 are in the 0.300-0.400s range.
When hitting app6 I'm seeing around 0.800s.

It's a shame mod_proxy_balancer doesn't grok geoip.  It'd be fun for
it to default North American users to our US app servers, .EU to
Telia, with the fallback to use any of the others that are alive...

Anyone up for some coding? :-)
