They are not equivalent, NFS_Commit = true forces all operations to the FSAL to be sync. Use of async on knfsd is not fair to use in performance evaluation. I have long lobbied for renaming the async option to "I don't care about my data." The option means that knfsd lies about whether data is actually synced to disk or not. We were very purposeful in NOT replicating knfsd's async option with Ganesha. I have in the past handled service calls for knfsd users who used async and then had data integrity issues...
