Subject:  Debian power consumption

 
Debian binary programs are compiled to run on all 32 bit Intel processors
except the 80386.  That is, all processors after 80486 are supported.
The 80486 appeared in 1989. 
 
  Debian: Supported Hardware
  http://www.debian.org/releases/stable/i386/ch02s01.html.en

Debian binaries do not use instructions that are available only on
CPUs newer than the 80486, including the Pentium.  Some projects have
optional source code that use MMX/SSE (SIMD) instructions.  They cannot
be used, for 80486 does not support SIMD.  For this reason Debian
programs are slow.

Another factor that makes Debian slow is the large kernel.  The default
kernel has many features that are rarely used.  In addition it must
run on the old 80486.  This makes the kernel large and slow.  Some
Debian users build (compile from source) their own kernels to improve
performance.

Apple controls both the hardware and software it sells.  Apple can
tune compilation flags and use all the new CPU features to get the
most out of the hardware.

Debian 二进制程序可以运行在所有除了 80386 的 32 位 Intel 处理器上。也就是,所有的 80486
以后的处理器都支持。80486 从 1989 年就开始出现了。

Debian 二进制不使用仅在 80486 包括奔腾处理器以后出现的指令。一些项目有一些可选的源代码使用
MMX/SSE(SIMD)指令。它们不能被使用,因为 80486 不支持 SIMD。因此,Debian 程序比较慢。

另一个导致 Debian 慢的因素是大内核。默认内核有许多很少用到的特性。另外,它必须运行在老的 80486 上。这使得内核又大又慢。一些
Debian 用户编译(从源码编译)他们自己的内核来提升性能。

苹果公司控制了他们所销售的硬件和软件,他们可以调整编译参数并使用所有新的 CPU 特性以尽量发挥硬件的功能。

晕了,怎么没有看出来是电源管理的。
