are you sure you are not referring to 1 million products. I run in the real world over 100,000 products. I have approx 18 top categories with 3-10 levels of sub categories. if your see 1,000,000 categories that way then it is feasible. I use automated updating from my suppliers to keep thing up-to-date. these updates happen every 24 for prices new and obsolete products. availability is as often as 15 min. The average Cpu usage during these operations is about 15% of a 1.6ghz Cpu with enough RAM to not use the swap file. the peak cpu usage is about 75% when the scheduled services and large imports (1 gig data) are happening.
