openssh unix dev - Mar 2013 - compression only in one direction

Hi,
I know that it is possible to enable or disable compression.
I just learned that the protocol would allow for one-way negotiations for things
like how to encrypt the traffic, hash it, compress it.

Many people have very asymmetric internet access bandwidth.
e.g. 1 mb download, only 100 kb upload

Would it not be useful to be able to compress only outbound traffic in such a
situation?

[Sorry for the top post. I hate Outlook.]

How much CPU does SSH take for compression? (I have never benchmarked it.) I
have never noticed an issue with hit impacting a machine when compression is
turned on. Seems like more pain that it is worth.

Probably not - asymmetric transport options are pretty confusing and AFAIK
no client supports actually selecting them. I consider them to be a protocol
feature that seems nice in theory but isn't useful in practice.
