It should be possible to +achieve full line rate on dual core systems but OS and data management overhead makes this +more difficult to achieve. The cipher stream from MTR-AES-CTR is entirely compatible with single +thread AES-CTR (ST-AES-CTR) implementations and should be 100% backward compatible. Optimal +performance requires the MTR-AES-CTR mode be enabled on both ends of the connection. +The MTR-AES-CTR replaces ST-AES-CTR and is used in exactly the same way with the same +nomenclature. +Use examples: ssh -caes128-ctr you@host.com + scp -oCipher=aes256-ctr file you@host.com:~/file + +NONE CIPHER: +To use the NONE option you must have the NoneEnabled switch set on the server and +you *must* have *both* NoneEnabled and NoneSwitch set to yes on the client.

The connection attempt will fail with an +error if a client requests a NoneSwitch from the server that does not explicitly +have NoneEnabled set to yes. Note: The NONE cipher cannot be used in +interactive (shell) sessions and it will fail silently. Set to no by default. + +HPNDisabled=[yes/no] client/server + In some situations, such as transfers on a local area network, the impact +of the HPN code produces a net decrease in performance.

Conceptually this is similar to the TcpRcvBuf +option as applied to the internal SSH flow control. This value can range from +1KB to 64MB (1-65536). Use of oversized or undersized buffers can cause performance +problems depending on the length of the network path.
