These devices don't look like NFS, but you have: > mmap_disable: yes > mail_nfs_storage: yes > mail_nfs_index: yes So what filesystem is that? Are they storing only mails, or other stuff too (like logs)? The mail_nfs_*=yes are probably not needed and are slowing things up at least somewhat.. > lda: > fsync_disable: no This is explicitly set for LDA, but it's the default already elsewhere. Maybe you wanted to try fsync_disable=yes elsewhere except in LDA?
