Tobias Zagorni created ARROW-16712: -------------------------------------- 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). -- This message was sent by Atlassian Jira (v8.20.7#820007)
