Sorry,the true results are: Actual results: nfsiostat show ops=256k Expected results: nfsiostat show ops=1024k Please try it with the latest nfs-utils version.
Seems I cannot reproduce your problem:

Therefore, it is being closed. If plans change such that this issue will be fixed in an upcoming release, then the bug can be reopened. |
