I've tried running with and without HTT enabled on it. My observations were that it seemed to help slightly with certain tasks but in general degraded system performance. For example, if i build a world to upgrade the OS it takes at least 30 seconds longer with HTT enabled. I tried it multiple times to verify it. I even tried it with different values for the j flag. (3 4 5 and 6) Similarly, if i run it in windows with HTT enabled I noticed that windows was peppy but it was a disaster during gaming. Of course that makes sense as most of my games are not designed for multiple cpus. (enemy territory, quake 3, Doom 3, etc) I also realize i could play some of them in fbsd, except my radeon 9600 xt isn't supported for 3d acceleration!
