Clients Feature ComparisonΒΆ

For the ssh2-python (libssh2) based clients, not all features supported by the paramiko based clients are currently supported by the underlying library or implemented in parallel-ssh.

Below is a comparison of feature support for the two client types.

If any of missing features are required for a use case, then the paramiko based clients should be used instead. Note there are several breaking bugs and low performance in some paramiko functionality, mileage may vary.

In all other cases the ssh2-python based clients offer significantly greater performance at less overhead and are preferred.
