I had to smile at Chris Wolf blog post about performance – it pokes a little fun at us instructors – who when asked a question – respond “It depends…”
In fairness. It quite often does “depend” – on many variables that are almost to completely nail down. In fact I say “It depends…” so often that I’ve sometime toyed with having it printed on one of my VMware polo shirts – not that a brand polo shirt, baseball cap, cup – and other merchendising wearing instructor. Its a choice between “It depends” and “Don’t forget August the 12th…”
Chris’ post centres around some claim and counter-claim about performance in the old chestnut of MS Vs VMware Vs Xen debate – that will be rumbling on into the next decade if current traffic persists. Personally, as soon as performance claims or TCO/ROI claims are made by any vendor their website – I start to sniff there air. Have you ever been on a vendors website that say “Our product has exceptionally poor performance which falls well below any of our competitors – and will inceases your TCO and decrease your ROI”?
