In attempting to diagnose why Solaris 11 installs are ludicrously slow
through Oracle OpsCenter, I came across the following nastiness:
It appears that pkg operations over SSL are mindbogglingly slow for
T5220 class hardware.
I know that the CPUs on that generation of "Niagra" hardware are weak,
but they do have an SSL accelerator. In dealing with scp transfers
within our network, I compared an internally compiled scp, to the
solaris-supplied scp, and the solaris scp which uses the acceleration
support, was significantly faster.
So I'm wondering if there is an issue with python not using the
acceleration hardware for ssl, or something?
Comparison numbers:

This may seem like a somewhat artificial test, but it matches up with
what matters: time to install solaris.
Doing an install of solaris over the https IPS url, took *3 hours* on
T5220, vs the expected 1hr or less.
