Using a much shorter test program (while sleep 1; do echo hello; done), I
observed that CPU load jumps from about 10% to 35% the very moment the console
screen starts scrolling. Resetting the terminal via reset and repeating the
experiment lowers CPU load again to 10% -- until scrolling starts.  Disabling
konsole history brings the CPU load down to constantly 2%. I used a buffer of
1000 lines. The test program "while sleep 1; do true; done" does not increase
CPU load.
