long ssh communication

Hi,

I connect from a debian machine with OpenSSH_3.8.1p1 to solaris 9
machines with Sun_SSH_1.0.1 using Perl modul Net::SSH::Perl. It takes
several minutes to run a command (who or something).

Connecting to a machine with OpenSSH (solaris 8) takes a second and
running ssh from a command line to solaris 9 Sun_SSH is also ok. Below
is debug output.

Could someone point me where to look at to cut down these times?
