Does auto-optimize mean auto-detecting that an SSD is in use? On my laptops with SSDs I force laptop mode on at all times with a 10 minute cache expiration. That's the single most useful change; it allows writes to be cached in RAM long enough that when they eventually get flushed, a higher percentage of the writes are sequential.
