             Summary: [C++] track how much is spent in allocation for a given operation
                 Key: ARROW-16712
                 URL: https://issues.apache.org/jira/browse/ARROW-16712
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Tobias Zagorni


While profiling ARROW-16161, Memory allocation would sometimes appear to take up a few percent of total runtime. Especially the creating/copying of CPUMemoryManager objects seems to be more costly then then allocator calls themselves at times. It would be good to see how much different operations are affected by this (possibly even distinguish between time a Pool allocation and in the allocator itself).
