Performance engineering from the model down to the metal, then out to the node and the cluster.

The tree below is the whole note: a section, then sub-notes, then sub-sub-notes. Open a chapter to work inside it. Previous and Next walk the document in order. For the shared-machine habits these pages assume, start with [Working on a shared cluster](/notes/working-on-a-cluster).
