Red Hat 6.3 SSH Connection Delay

Noticed that there is a delay of about 10 seconds when connecting via SSH on Red Hat Enterprise Linux 6.3. Basically an SSH connection to a Red Hat server freezes for a long time. Here is what I did to correct the situation:

# sed -i -e 's/#GSSAPIAuthentication no/GSSAPIAuthentication no/g'
-e 's/GSSAPIAuthentication yes/#GSSAPIAuthentication yes/g' /etc/ssh/sshd_config

# service sshd reload
