Compression level
  Specify the level of compression for transmission. The more right, the more compression is done (note: it may degrade the throughout with a high speed link such as ADSL or FTTH).
  By using SSH1 protocol, when the Compression level is 0, the packet compression is diabled, or the Compression level is over 1, the compression is enabled.
  By using SSH2 protocol, use the Compression order to enable the packet compression. And then, set the Compression level to 1 over.
