Net::SSH::Perl slow to login.
I have some sample code that's supposed to ssh to another machine using Net::SSH::Perl, execute a command, and print
the output of that command. It's very basic, and it works. However, I noticed that upon logging in:
Code:
$ssh->login('username','password');

It takes roughly 10-13 seconds to complete. After that, executing the commands are fast, but I'd like to be able to shorten
the lengthy login process. Have any of you experienced this? I believe I'm using SSH2. When I try to use SSH1, it kicks back
an error about Math::GMP:

Code:
localmachine: Reading configuration data /export/home/user/.ssh/config
localmachine: Reading configuration data /etc/ssh_config
localmachine: Connecting to server.com, port 22.
localmachine: Remote version string: SSH-2.0-Sun_SSH_1.1.3
