At 2010 IIUG conference, when Jack Parker saw the preview of Informix warehouse accelerator, he offered his Amex card to buy the product. Two problems: I couldn't sell since the product was not released. I presume his Amex card has some credit limits :-) I suspect, after that incident, Jack started working on his performance tuning in the old route and produced nice article on Informix Performance tuning (part 1).
Note to Jack -- Good news is Informix Ultimate Warehouse Edition with Informix Warehouse Accelerator is now GA. You can buy it any time, even with your Amex.
