[zfs-discuss] Sync Write - ZIL log performance - Feedback for ZFS developers?

Later when the txg commits then the blocks are just linked into the txg. However, this processing is not done if there are any slogs because I found it didn''t perform as well. Probably ought to be re-evaluated. Won''t this affect NFS/iSCSI performance pretty badly where the ZIL is crucial?
