Hi Jim,
I figured out how to get the ForensIT User Profile Manager 2.1 working
and mapped any new user to use a local profile that already exists and
that definitely speed things up, it knocked down the login times roughly
in half to about 39 seconds and I bumped up the memory from 1.5 GB to 2
GB and added a second processor and that knocked down the login time to
33 seconds. I don't think saving the 6 seconds is worth the added memory
and processor allocation.

<div>If login times are substantially longer than a similarly
configured physical machine, you likely have a storage
bottleneck. Startup and login are the two highest I/O times. Do
you have any solid state drives or highspeed cacheing in your
storage environment? You may be attempting to address a hardware
problem on the software level. Although, optimizing your login
surely won't hurt anything.</div>
