All financial systems don't care about time. Prety much all financial transactions are settled with a given date, not instantly. Go sell some stocks, it takes 2 days to actually settle. (May be hidden by your provider, but that how i

Committing to NVMe drive properly is really costly. I'm talking using O_DIRECT | OSYNC or fsync here. Can be in the order of whole milliseconds, easily. And it is much worse if you are using cloud systems.
