It turns out the "Optimizing Linux performance on SDX" whitepaper was "expired" because it hadn't been properly branded with the HPE format. We're working to reformat and repost the document shortly. I'll post an update in this forum when it's back online.
If someone wants a copy in the meantime send me an email and I'll send you a copy. The only planned technical changes will involve some recent findings with power-savings on the v3/v4 processors. We've found that recovery from various C-states is much better on the latest processors. *Some* workloads will benefit if some cores are in a power-saving state since the active cores are then able to turboboost.
