12.8. How cool is FreeBSD?

問: 有人做過 FreeBSD 執行時的溫度測試嗎? 我知道 Linux 比 DOS 涼, 但沒聽人提過 FreeBSD. 似乎很熱.

A. No, but we have done numerous taste tests on blindfolded volunteers who have also had 250 micrograms of LSD-25 administered beforehand. 35% of the volunteers said that FreeBSD tasted sort of orange, whereas Linux tasted like purple haze. Neither group mentioned any particular variances in temperature that I can remember. We eventually had to throw the results of this survey out entirely anyway when we found that too many volunteers were wandering out of the room during the tests, thus skewing the results. I think most of the volunteers are at Apple now, working on their new ``scratch and sniff'' GUI. It's a funny old business we're in!

不開玩笑了, FreeBSD 和 Linux 都使用 ``HLT'' (hald) 指令 以在系統閒置時降低電力的使用也減少了熱的產生. 如果有設定 APM (automatic power management), FreeBSD 也可以讓 CPU 進入低電力 模式.
