You do realize that there are many more variables for such a test than just "1080p video" and "make -j64 buildkernel"? Let's not forget about hardware, video drivers, player capabilities, exact kind of the video (you know, 1080p alone doesn't tell much). Besides, someone might be interested in running -j64 on his 1,2,4-core desktop system, but it's definitely not me. I prefer to be reasonable. I am not saying that our scheduler (ULE) is perfect. I don't even say that it's better (in whatever comparison system) than Linux scheduler X. I say that I wouldn't spend my time improving system behavior in a scenario like this. I compile stuff very frequently (kernels, ports, world) while browsing web, reading email, doing various "desktop stuff", sometimes watching videos from the web (like e.g. trailers). On this machine/hardware I have never personally felt a need for improvements in the scheduler. And I run KDE4 with all bells and whistles enabled. YMMV. P.S. I don't discourage anyone from improving our scheduler, I even do encourage that. -- Andriy Gapon _______________________________________________ freebsd-performance@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-performance To unsubscribe, send any mail to "freebsd-performance-unsubscr...@freebsd.org"
