I'm on an atom-powered (read: under-powered) netbook, which is nevertheless sufficient for most of my needs (it has good graphical acceleration for videos and 2D graphics such as the browser, and terminal operations with sh are inherently quite fast).
The biggest pain point of the setup is that all gtk-based terminal emulators seem to be really slow (scrolling is slow, and I need scrolling for reading man pages--it really sucks when you can't go RTFM properly).
xterm and konsole are fast. (Tty's are the fastest but sometimes I want a terminal next to a browser window.) On the other hand, gtk-based terminals integrate better with MATE (I tried gnome-terminal, guake, mate-terminal and a couple of others and they all scroll slow compared to konsole and xterm, which both scroll fluidly).
What could be the cause of the speed difference and could gtk-based terminals be made as fast as xterm or konsole?
