charset=UTF-8 Content-Transfer-Encoding: 8bit Hi David, I’m just checking in on this patch to see if you’ve had a chance to review the benchmark results I shared last week. To recap, the caching reduced the execution time for the NUMA_NO_NODE case from ~2402 ns to ~453 ns in my test environment. Please let me know if the performance gain justifies the change in your view,or if you would prefer I send a v2 that simply updates the TODO comment as you suggested. Thanks, Swaraj
