Do you have any resources that help explain these SAS performance measures? A book perhaps?

I have been trying to help with exactly this (and your breadcrumbs help) but it is tricky for me since I am used to open source/*nix environment where you can use much different tools and also information and tutorials are distributed much more widely.

Unfortunately not. With SAS I never used books and relied solely on having access to the fully licensed system at a previous job and all of the SAS PDFs floating around the internet and findable with specific searches.

That combined with a general computer science background and you can start to put the whole thing together.

I'd be lying if I said I hadn't considered writing one, but at my age I'd honestly ask why write one for an old proprietary system and make business for someone else when, if I'll ever go back long term, they can pay me an exorbitant amount as a consultant. Might as well start writing 'the dark arts of COBOL' :p
