I use MIPS/Watt to measure energy efficiency. Low power devices can be very energy inefficient if they also have a poor performance. I host my website on an ARM system that only uses 10 W (idle). It has the same processor/clock-speed as the DreamPlug. This system is very low power but it can only just cope with the load. To give you an example: Generating my homepage takes about 2.5 seconds. This is not wrong, it's still acceptable. To measure the performance of my new system, i decided to test a small project i'm working on. This project is a no-database version of my blog programmed in python (currently version 0.01). I compared homepage generation on both my ARM and my Intel system. Results: ARM - 25 Pages/second Intel - 800 Pages/second In this test the Intel system has over 30 times more performance. (Note, this is not a "hello world" test, the Intel system managed to use half the bandwidth of my gigabit LAN) Rob. http://freedomboxblog.nl _______________________________________________ Freedombox-discuss mailing list [email protected] http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/freedombox-discuss
