You say "optimize", but I don't see anything there that actually requires using app_info or app_config.
For AP27, as far as I can tell, the XML you list has no effect at all and would run AP27 exactly the same way as it would normally run.
For PPS-DIV, it's running with 7 threads, which, although not being the default behavior, is something you can do with the control on the project preferences web page.
App_info or app_config isn't needed for either.
What exactly are you trying to accomplish?
