That's actually not true at all. No one who cares about nanoseconds is using kdb+ for a production trading system.

It's primarily used for trading research and surveillance, not live trading. And I've never heard of anyone running it without an OS.

For those curious, what they're actually using is FPGAs and custom silicon.
