Unfortunately, Chilkat v9.4.0 does not implement compression for the transport. This should be implemented by v9.4.2.

According to the SSH Protocol standard (RFC 4253), the following compression methods are defined:

      none     REQUIRED        no compression
      zlib     OPTIONAL        ZLIB (LZ77) compression
The standard states that a server is REQUIRED to accept the "no compression" option. A server that is configured otherwise should expect problems such as what you've encountered.
