由于本文重点是使用QEMU开发测试跨平台软件，可能会包含少量的硬件交互，我重点介绍系统模拟。
Because the point of this article is using QEMU to develop and test cross-platform software, which may entail subtle hardware interactions, I emphasize system emulation.
我想知道这一差异如何影响CPU性能，所以修改了POWER 6硬件上的概要文件以使用专用的CPU。
Curious about how this difference could affect CPU performance, I changed the profile on the POWER6 machine to use dedicated CPUs.
当站点需要较高的安全级别时我更倾向于第二种方法，并且当人们抱怨使用SSL如此之慢时我会反问他们为什么不购买更好的硬件加速它的执行。
I prefer the latter approach for sites that require high security, and when people complain that SSL is slow, I ask them why they haven't bought hardware to accelerate it.
