The NCurses library is really efficient at that:

Maybe if it comes to "initializing the sources..." - downloading several
files withs lots of Progress screens - then it sends quite of lot of
screen changes per second. Maybe I'm wrong but this is my feeling from
how I understand Roberto's question.
Yes. They are asking if there's a way to limit/reduce/elliminate all that output.
Let me explain why? Their systems are multi-node systems. So they could be
upgrading anywhere from 8-300 nodes simultaneously. So no one is going
to be looking at these installs. And to make matters worse, some of their
customers only allow say 20/30 minutes to upgrade a node
because their core critical business is dependent on these nodes running
customer product. So anyway to reduce that upgrade time is a plus and oh
BTW, they know that turning off the SOL connection decreases the install
time, but like I said this is a requirement.
