Jacob Wujciak-Jens updated ARROW-17281:
---------------------------------------
Description:
On Windows 10 Version 10.0.19044 Build 19044 {{CpuInfo::CacheLevel}} over
reports the L-cache size:
640K for L1
10M for L2
These values are also reported by Windows resource monitor.
It seems that windows is reporting the total size of cache for each core
aggregated as one value. Possibly due to "intel smart cache" cache sharing?
