In attempting to diagnose why Solaris 11 installs are ludicrously slow

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?
pkg(5) uses pycurl for all of its transport needs which is just a
wrapper around libcurl.
libcurl uses libopenssl, which as far as I know, automatically uses the
crypto acceleration available.
I'm uncertain why Python would be implicated here.
If this is truly a crypto acceleration issue, then the same issue should
show up with curl.
Perhaps more data is required before analysis can be performed.
