> memory latency is orders of magnitude higher than the algorithm execution
> time, but better for us.

be
> better for the encoder = lower bitrate needed.
>
> 2. Made double threshold default, single optional, and optional scaled
> quality setting for double (one 0-255 integer instead of 4 pixel
> thresholds).
>
> 3. Toned down filter thresholds so it will be acceptable for a much wide
> range of video/users.

> 3. Tweaked prefetch, a few percent faster total.
