这一选项针对x86系列的CPU使用更多的常规优化。如果你在上面一项选的是i386、i586之类的才选这个
[*] HPET Timer Support
HPET是替代8254芯片的下一代时钟处理器。这里你可以安全的选上这一选项。如果硬件不支持的话,将仍使用8254时钟处理器
[*] Symmetric multi-processing support
对称多处理器支持,在单CPU的机器上,不选这个选项会更快一些。由于超线程技术,看起来是两颗CPU,因些要选上这个选项
(1) Maximum number of CPUs (2-255) 支持的最大CPU数 [ ] SMT (Hyperthreading) scheduler support [*] Preemptible Kernel
这个选项能使应用程序即使内核在高负载时也很可靠,建议最好选上
[*] Machine Check Exception
这个选项能让CPU检测到系统故障时通知内核,一般我用组装的台式机会选这项。

这是一种电源管理方式,你可以看看你的BIOS是否支持。如果支持的话建议你选上这项
