Make tcmalloc cpu cache size consistent
Last update date:

Affected products:
MongoDB Server

No affected releases provided.
Fixed releases:
8.0 Required
Description:
Info
SERVER-88085 changed it so that we set the cpu cache size on static initialization time through adding in a custom setting when initializing the cpu caches. However, we need to call SetCacheLimit() to update the global understanding of cpu cache size as well. Furthermore, we can delete the non-functional code in tcmalloc_set_parameter that "sets" the cpu cache size.
