STAC Report Links Update Rate to Power Consumption
Securities Technology Analysis Center has released the detailed report on its study of OPRA data through Wombat on Sun/AMD servers and Solaris 10. Interestingly, the report relates performance results to specific cost drivers, introducing metrics such as “updates per watt”.
Let us know what you think of measurements such as”updates per watt. Is this a useful measurement? What similar measurements - comparing update rates or latency figures to cost drivers - do you feel are important? Leave us a comment.

Measurements involving energy and power may turn out to be useful, but I think we’ll need to see numbers published for competing systems to know for sure. I applaud STAC for innovating in this area and will watch with interest for future results.
If hardware for feed handlers is purchased based on energy consumed, then idle power consumption should probably also be considered. Over the life of the hardware, it’s quite possible that more energy would be consumed when markets were closed and the hardware was idle than when markets were trading.
Measuring work done for energy consumed might mislead managers who don’t know that some energy is consumed even when zero work is being done.
