> Right now, we use EMA for the smoothing calculation of the throughput. But
> there is an idea to use EMA on the buffer debloat(BufferDebloater) level
> because it contains more information(old buffer size, current throughput,
> buffer in use count, etc.) and it looks like it should be used more
> effectively.
> !NB. This is just an idea which makes sense to try. but if the new
> implementation doesn't have real profit it makes sense to keep the old one.
