"At a particular include level" is important, because the optimization
only helps if there are many includes at a particular level: For
example, if object A includes object B, which includes object C and no
object is cachable, they still need to be fetched in order: The
object is cacheable, they still need to be fetched in order: The
request for B can only be started once A is available, and likewise
for B and C.
To summarize:
* Parallel ESI can *substantially* increase the response times for ESI
if cachable objects include many uncachable objects. The maximum
if cacheable objects include many uncacheable objects. The maximum
benefit, compared with standard, serial processing, is achieved
through parallel ESI in cases where all nodes of an ESI tree are
cacheable and at least some leafs are not.
