Rewrapping occurs and has a performance impact the moment you resize. On my average laptop, rewrapping takes around 0.2 seconds with a scrollback buffer of 1 million lines. Most people use a scrollback buffer somewhere between 1000 and 10000 lines, hence the performance penalty is negligible. Gnome-terminal allows you to have infinite scrollback, if it grows beyond a few million lines and then you resize the terminal then it's going to be really slow. For this reason, we plan to make rewrapping configurable so you can turn it off if you prefer giant scrollback and want to resize quickly.
