Con's original submission was to me, quite an improvement. But I have to say it, and no denegration of your efforts is intended Con, but you did 'pull the trigger' and get this thing rolling by scratching the itch & drawing attention to an ugly lack of user interactivity that had crept into the 2.6 family. So from me to Con, a tip of the hat, and a deep bow in your direction, thank you. Now, you have done what you aimed to do, so please get well. I've now been through most of an amanda session using Ingo's "CFS" and I have to say that it is another improvement over your 0.40 that's is just as obvious as your first patch was against the stock scheduler. No other scheduler yet has allowed the full utilization of the cpu, and maintained user interactivity as well as this one has, my cpu is running about 5 degrees F hotter just from this effect alone. gzip, if the rest of the system is in between tasks, is consistently showing around 95%, but let anything else stick up its hand, like procmail etc, and gzip now dutifully steps aside, dropping into the 40% range until procmail and spamd are done, at which point there is no rest for the wicked and the cpu never gets a chance to cool. There was, just now, a pause of about 2 seconds, while amanda moved a tarball from the holding disk area on /dev/hda to the vtapes disk on /dev/hdd, so that would have been an I/O bound situation. This one Ingo, even without any other patches and I think I did see one go by in this thread which I didn't apply, is a definite keeper. Sweet even. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
