Jonathan Keane commented on ARROW-12316: ---------------------------------------- I've attached the two reports I've compiled. The first (unmarked, memory_allocators.html) is on macOS, the second (marked ubuntu) is on ubuntu. > [C++] Switch default memory allocator from jemalloc to mimalloc > --------------------------------------------------------------- > > Key: ARROW-12316 > URL: https://issues.apache.org/jira/browse/ARROW-12316 > Project: Apache Arrow > Issue Type: New Feature > Components: C++ > Reporter: Neal Richardson > Priority: Major > Fix For: 4.0.0 > > > Benchmarking shows that mimalloc seems to be faster on real workflows (at > least on macOS, still collecting data on Ubuntu). We could switch the default > memory pool cases so that mimalloc is preferred. > cc [~jonkeane] [~apitrou] -- This message was sent by Atlassian Jira (v8.3.4#803005)
