Whenever disk IO is involved, all bets are off ! Parenthetically, everyone is in awe today with respect to milliseconds trading brokers as well as doctoral-level modelling chaps just by looking at the shape the economy is nowadays ! The fruits of their toil are here for everyone to observe. Another point is that arguably only in-memory database can consistently ensure this kind of query response time.

Point taken there...and I'd agree. I cannot think of anything that would be ms within BI. Unless it is a top-secret gov't project! “I was referring to BI queries”.

But, you do have a point. The response time for the financial trading systems is very low, probably mili or centi seconds. I'll have to ping some of the customers I work with in Chicago to find out more on this. I guess the reason I poked fun of this is that Oracle's SQL*Plus only reports time to two places, centiseconds. @Greg

Look into the very large areas of financial trading...anything from stocks to futures, options, and so on (in any country in the world). Almost every exchange in the world measures their query performance in milliseconds. I thought it a joke, until I saw how competitive it was to 'beat' out other brokers in a live trade. Trading houses that try to gain competitive advantages against one another sometimes have small 2-4 man doctoral-level research teams to get their response times down and do measure the times at this level. And it's not just the database queries they look at...it's a whole group of other things as well! As for other industries, I don't know of any that would require it, let alone put lots of energy into attaining that response time. “I simply can’t stop laughing at the fact that there needs to be precision below 1 second.” Look into the very large areas of financial trading…anything from stocks to futures, options, and so on (in any country in the world).
