一、查看CPU信息

~ # cat /proc/cpuinfo
processor       : 0
BogoMIPS        : 48.00
Features        : fp asimd evtstrm aes pmull sha1 sha2 crc32
CPU implementer : 0x41
CPU architecture: 8
CPU variant     : 0x0
CPU part        : 0xd03
CPU revision    : 4processor       : 1
BogoMIPS        : 48.00
Features        : fp asimd evtstrm aes pmull sha1 sha2 crc32
CPU implementer : 0x41
CPU architecture: 8
CPU variant     : 0x0
CPU part        : 0xd03
CPU revision    : 4

二、查看当前操作系统的缓存行大小

~ # cat /sys/devices/system/cpu/cpu0/cache/index0/coherency_line_size
64

三、查看不同层次的缓存大小

~ # cat /sys/devices/system/cpu/cpu0/cache/index0/size
32K
~ # cat /sys/devices/system/cpu/cpu0/cache/index1/size
32K
~ # cat /sys/devices/system/cpu/cpu0/cache/index2/size
256K

四、查看内存信息
