Niall Litchfield is a DBA of 15 years standing, with extensive experience of running databases on various x86(64) platforms, and with a particular bias towards Microsoft Windows. Niall began professional life as a ""bean-counter"" for KPMG, consequently he is a DBA who respects auditors, not least because they have to stand in unheated warehouses in the middle of winter watching other people count things, something he never wants to do again. His dad was a real engineer crafting genuinely useful objects with fine tolerances and that, coupled with an early experience in which he showed that the two competing macro-economic theories of the time both explained actual behavior equally well, and that neither explained it adequately, rather explains his evidence based approach to databases in general and performance tuning in particular.
