Universe loading very slow

Problem description
We are having 10000 objects in Universe. When we import the Universe in Universe designer, in some machine it is opening in rapid speed.
But in other machine it is taking a lots of time. Some time it shows not responding in task manager. But open after 15 minutes

Answer:
This is because in "Tools>Option> Graphics " tab the "underline Keys" is checked.

It actually check all the tables added in the Universe.
If you remove the check it will first open the universe for you without checking all the tables. This is not a good practise but to handle an universe like 10000 object it is almost mandatory
