Comparing some Big Numbers

Strictly for amusement only. Paul Buchheit: The secret to making things easy: avoid hard problems

If it weren't so easy to make easy problems hard, especially when you're at it full-time ..."How is a human going to be able to process that amount of information?"

5000 marketing messages per day in urban areas."With the spread of computerized trading--electronic trading now makes up 60% to 70% of the daily volume on the NYSE and algorithmic trading close to half of that--the manic floor traders look to be headed the way of the exchange's in-house barber (long gone)."

"The fastest systems, running from traders' desks to exchange data centers, can execute transactions in a few milliseconds--so fast, in fact, that the physical distance between two computers processing a transaction can slow down how fast it happens."

"In the past, traders used consolidated feeds--market data updates such as those provided by Reuters and [create Thomson]. Distributing those feeds, however, could take up to 500 milliseconds, far too long for today's automated trading."

'"Our customers don't like variance."'
