> [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
> Priority: Minor
>
> 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?
