Google Plumbing Stat

Amit Agarwal, a professional blogger and personal technology columnist for a national newspaper, wrote “Single Google Query Uses 1000 Machines in 0.2 Seconds” here. The data came from Googler Jeff Dean, a former Digital Equipment wizard who joined Googzilla 20 patent documents ago. Key points for me were:
- One query uses 1,000 machines
- The Google index is in memory
- Latency now 200 milliseconds, down from 1000 milliseconds
- Power consumption… a lot.
Hopefully a video of Dr. Dean’s talk with turn up on the Google Channel.
