ODX file transfers run slower than expected in Windows Server 2012


File transfers that use the Windows Offloaded Data Transfers (ODX) feature intermittently take longer than expected.


This issue occurs because the TRIM command takes longer than expected. Therefore, the ODX file transfers are slower than expected.


Microsoft is currently investigating some performance improvements for the TRIM and the UNMAP commands. However, this functionality is very dependent on the storage vendors' implementation. Therefore, you should make sure that your storage software and firmware are up to date.
