There is no much available. Intel Optimisation guide can help you much if you know what are you looking for. It is huge document and many of perf suggestions are targeted to compiler developers and assembly coders. From VPP perspective sample plugin might be good start, if you have any particular questions, drop email here and we will try to explain... -- Damjan
