I'm not the OP but I'm using ssh without -c.  The ssh man page says:

   Compression is  desirable on modem lines and  other slow connections,
   but will only slow down things on fast networks.

Ssh goes over a VPN which does compression.

I wouldn't mind having to add a dozen commands to my .emacs
but as far as I can tell, it can't be configured off.
