cengal_cpu_info

Extended, cached CPU info with consistent output format.

Advantages

Much faster: milliseconds instead of tens of seconds to gather required information thanks to lazy gathering: will gather only info you need.

Consistent output format of memory-related values (unlike backend 'py-cpuinfo' package). Provides additional information. Provides cached instance (backend 'py-cpuinfo' package requires several seconds per an each call to gather CPU information).

Installation

pip install cengal_cpu_info

Documentation

Import

from cengal_cpu_info import cpu_info, CpuInfo

Cached instance

ci: CpuInfo = cpu_info()
