--------------------------------------
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).
