(except for my bias against linux of course) Linux has some really poorly-performant code, possibly resulting from poor device drivers in some cases (though they have some good ones too, no doubt). I noticed that interactive performance on a Dell machine was terrible under moderate disk load (it would terribly degrade concurrent disk users, and I'd get mouse pointer lag of up to 10 seconds in X). I see none of this having upgraded to FreeBSD on the same hardware.
