This bug was initially created as a copy of Bug #2371495 I am copying this bug because: 7.1 backport Description of problem: Customer is experiencing a significant degraded performance when executing a file split/move operation (1 million line file is split into 50,000 files) and files are moved to different directories Version-Release number of selected component (if applicable): ceph 18.2.1-298 (7.1z3) odf 4.14.17 How reproducible: Always at the customer site. This is occurring in 3 of the 4 clusters. Steps to Reproduce: 1. Receive 4 1 million line files from mainframe 2. Execute a split/move operation to break up 1 of the million line file into 50,000 files and move files to different directories. Actual results: File splits and moves are significantly slower than they were prior to the upgrade. Expected results: File splits and moves should produce similar performance as on the older version. Additional info: The cluster which does not experience the issue is running older version of ceph/odf/ocp version (4.12)
