Note: every time the program needs to set the foreground color of the following characters, it does so by sending what it's known as ANSI escape codes. These escape codes are sent along with the characters that are printed on screen (they're also sent through the standard output). That means, the more color changes the program sends to the terminal, the more characters are sent and the less performance it gives. The number of characters in the Resolution column only takes into account the number of printable characters, effectively excluding ANSI escape codes.
