  Really more of a question about Builder than Sinatra. The instruct!
method takes optional arguments, unfortunately you either take the
defaults or override everything so

       xml.instruct!(:xml, :version => '1.1', :encoding => 'UTF-8')

Well this depends somewhat on your actually application, somewhat on
the server os, and somewhat on how you'd deployed it
(mongrel/mongrel-cluster/passenger/???) This is the same for Sinatra,
Rails or any other server app.

Processing delays might mean that you don't have enough daemon
processes, if they are all busy when a new request comes in, the
request will need to wait, either for a daemon to finish, or a new one
to be spun up.  It also may be that the server os is swapping
processes out due to memory over-utilization.  So there are quite a
few variables here.
