>From the ssh man page:

-C      Requests compression of all data (including stdin, stdout,
stderr, and data for forwarded X11 and TCP connections).  The
compression algorithm is the same used by gzip(1), and the ``level'' can
be controlled by the CompressionLevel option for protocol version 1.
Compression is desirable on modem lines and other slow connections, but
will only slow down things on fast networks.  The default value can be
set on a host-by-host basis in the configuration files; see the
Compression option.

... I'd recommend you experiment with different compression settings to
see if they have an impact on your results.  Note that you might already
be using compression, and benefit from turning it off.
