I'm having some serious issues with performance however - the 5400 is mind-numbingly slow compared to, well, anything. Whenever I do any disk intensive activities (e.g. untarring the ports tree), things slow to a crawl, and tar spends most of it's time sleeping according to top. This seems to happen no matter which box I stick this in (I've tried an old p233/intel chipset mobo and a k62/400/ali board), and seems to occure in both 5.0-current as well as 4.5-rel. I've tried Openbsd 3.1 on the same hardware config and things don't seem nearly as lagged, although performance is still not altogether impressive (takes 48 seconds to untar the ports tree on my old promise controller \w udma/66 drive with standard ata controller, 60 seconds to do the same under openbsd \w 3ware controller, and over 10 minutes to do the same under freebsd \w the 3ware controller). No error messages or syslog hints, no reliability problems as far as I can see, performance just seems to be inconsistent/awful. Anyone have any ideas? my dmesg is attached.
