This forum is a french forum, and as you might know, most of us do not speak english, neither can they read or write it ahah.
But well since I can I'll give you a short answer, even if there wasn't any question in the post, and thus you're almost making spam.
Power 8 server are mostly build to handle a lot of operation in the same time, it has a huge calculation broadband.
So if, as you said you run a "simple" application, it won't have better performance than any other processor, because that's not what it's intended for.
It needs to have a lot of data to process for Power 8 server to be better than usual computer or server.
