No, there are.  Look at the output of 'ps aux'.  However, I think the
slowness is our fault.

I'm surprised the people running the other applications aren't howling
at amaze, tbh.

I'm out of my depth, too.  I will notice that things are much better

Dario implemented has gone insane -- does anyone know how to turn that
