------------------------------------------
Summary: [C++] Windows reports aggregated L-Cache sizes
Key: ARROW-17281
URL: https://issues.apache.org/jira/browse/ARROW-17281
Project: Apache Arrow
Issue Type: Bug
Components: C++
Affects Versions: 9.0.0
Reporter: Jacob Wujciak-Jens
On Windows 10 Version 10.0.19044 Build 19044 {{CpuInfo::CacheLevel}} over
reports the L-cache size:
640K for L1
10M for L2
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?
