在Debian系统中,你可以使用多种方法来查看CPU缓存大小。以下是一些常用的方法:
lscpu
命令lscpu
是一个非常有用的工具,可以显示CPU架构信息。
lscpu
L1d cache
: 一级数据缓存大小L1i cache
: 一级指令缓存大小L2 cache
: 二级缓存大小L3 cache
: 三级缓存大小例如:
Architecture: x86_64
CPU op-mode(s): 32-bit, 64-bit
Byte Order: Little Endian
CPU(s): 4
On-line CPU(s) list: 0-3
Thread(s) per core: 1
Core(s) per socket: 4
Socket(s): 1
NUMA node(s): 1
Vendor ID: GenuineIntel
CPU family: 6
Model: 158
Model name: Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz
Stepping: 9
CPU MHz: 2796.000
BogoMIPS: 5592.00
Virtualization: VT-x
L1d cache: 32K
L1i cache: 32K
L2 cache: 256K
L3 cache: 6144K
...
/proc/cpuinfo
文件你也可以直接查看/proc/cpuinfo
文件来获取CPU缓存信息。
cat /proc/cpuinfo | grep -E 'cache_size|L1d|L1i|L2|L3'
例如:
cache_alignment: 64
address_sizes: 39 bits physical, 48 bits virtual

l1d cache: 32K
l1i cache: 32K
l2 cache: 256K
l3 cache: 6144K
...
dmidecode
命令dmidecode
是一个用于显示DMI(Desktop Management Interface)信息的工具。
sudo dmidecode -t processor
L1 Cache Size
: 一级缓存大小L2 Cache Size
: 二级缓存大小L3 Cache Size
: 三级缓存大小例如:
Handle 0x001C, DMI type 4, 42 bytes
