Due to the chaotic nature of dynamic adaptation, compressed result is not reproducible.

_note_ : at the time of this writing, `--adapt` can remain stuck at low speed
|

when combined with multiple worker threads (>=2).
|

* `--size-hint=#`:
|
||||
When handling input from a stream, `zstd` must guess how large the source size
|
||||
will be when optimizing compression parameters. If the stream size is relatively
|
||||
small, this guess may be a poor one, resulting in a higher compression ratio than
|
||||
expected. This feature allows for controlling the guess when needed.
|
||||
Exact guesses result in better compression ratios. Overestimates result in slightly
|
||||
degraded compression ratios, while underestimates may result in significant degradation.
|
||||
* `--rsyncable` :
|
||||
`zstd` will periodically synchronize the compression state to make the
|
||||
compressed file more rsync-friendly. There is a negligible impact to
