The output of ffsb in the latest 128 threads random odirect write benchmark was .... checking existing fs: /mnt/ffsb1 fs setup took 6 secs Syncing()...2 sec .... The corresponding output on 30 June was .... creating new fileset /mnt/ffsb1 fs setup took 847 secs Syncing()...1 sec .... It seems the filesystem used in the latest benchmark wasn't freshly created.
