Based on the results of multiple tests, the following information is updated.
Base: total used recalim total used Mem: 38Gi 2.6Gi ----> 38Gi 1.6Gi Swap: 5.0Gi 1.0Gi ----> 5Gi 1.9Gi used memory -1G swap +0.9g It means that most of the pages failed to move to the tail of the lru list, So we need to release an additional 0.9Gi anon pages to swap space.
Thanks again.
