the idle line (red) shows the relative power behavior of kernels/features when the system is idle. The http line (green) shows the same, but when the system is under a moderate webserver workload (a fixed amount of http requests per second of a dynamically generated webpage). Lower power is better obviously ;) the first picture shows that 2.6.23 is pretty much identical to 2.6.22 in the idle configuration, but saves about a watt in the http load situation. the second picture shows that tickless helps both idle and http by about 8 watts, and that then turning on the power aware scheduler helps the http workload by another 8 watts, while this scheduler feature doesn't help the idle workload (since there's nothing to schedule). _______________________________________________ Discuss mailing list [email protected] http://mail.lesswatts.org/mailman/listinfo/discuss
