Comparing performance of ssh to MVS and Solaris severs, respectively:

From Solaris to MVS:

133$ time ssh user@MVS         date
Mon Jul  8 07:43:06 MDT 2013

real    0m15.10s
user    0m0.07s
sys     0m0.01s

From Solaris to another Solaris:

134$ time ssh user@solaris     date
Monday, July  8, 2013 07:43:57 AM MDT

real    0m0.61s
user    0m0.15s
sys     0m0.01s

The MVS performance is awful (in the synchronic sense).
Is there any way to tell where the overhead lies, or
even whether ICSF is being used rather than ssh_rand_helper?

How does this compare with other users' experience?

(Once an interactive connection is established, response
is quite good.)
