This isn't about raw physics and biology but rather the use of business applications by users, specifically with regards to analytics and exploratory queries.

Anything less than a second to run a query and return results is considered "instant" (also sometimes "interactive") for analysis.

What? No human trades that quickly, and this is not about automated HFT trading systems but rather running database queries and what typical business users expect as "instant" results.
