I've never understood why Ubuntu takes a couple seconds to open a terminal window. I don't have a fast computer, but... it's a terminal window.

Try some lightweight terminal like sakura (my current preference) :)

.rc files are default. Unless the defaults are what make it slow?

Or your .bash_history might be very large.
