Guidance welcome.

Never mind.
Found it.
Thx to all who replied.  From that I found the CLI version.  Running. 
We'll see how well it does...

Even the GUI shouldn't be as slow as 30 hours, unless you don't have it
set to blank the screen after a minute or so. That's why the CLI version
is so popular with serious crunchers, it doesn't use any graphics at all
and is 1-2% faster per work unit.

I switched to the CLI recently myself so SAH could run all the time in
the background. Before I had the GUI running only as a screen saver and
blanking the screen immediately. Process times were about the same, but
I now turn out about 5-10% more work units per day because it's always
running. At low priority mode, it has little impact on most other
programs - online gaming is essentially unaffected by SAH.
