Slow at returning shell prompt on Ubuntu 14.04 LTS

Created by: dkfi

Everytime I hit the return key in a terminal (even with no command typed in), the terminal returns the prompt too slowly. The problem is even more noticeable when you keep the return key pressed... a common thing that a lot of people do to get some blank lines in order to make terminal output more readable.

I've put bash in "set -x" mode and this is what I get:

kristian@gem:$ ++ autojump_add_to_database ++ [[ /home/kristian == /\h\o\m\e/\k\r\i\s\t\i\a\n ]] +++ pwd -P ++ autojump -a /home/kristian kristian@gem:$

Is it really necessary to add the current directory to the database everytime the return key is pressed even if there wasn't any command given?
