SSH problem with dropbear on microblaze

[Utkarsh Kumar]

Hi,

I am using the default dropbear version 0.48 with uClinux-dist distribution
on microblaze processor. While trying to ssh its taking 60 seconds per
session i.e. if only one ssh session is opened it takes 60 seconds to
connect but if 2 sessions are opened simultaneously, it takes 120 seconds
for the 2nd session. same way for n session it take n*60 seconds for the
nth session to connect.

Request you to help me achieve the followings:
1. How to reduce the time to connect ssh (currently its taking 60 seconds)
2. How to reduce the time for the subsequent sessions, if opened
simultaneously.

Please find the logs below:

#ssh -v 10.213.12.11
