Do you have any numbers on how gnome-terminal is a resource hog? The numbers return by top/System-monitor/etc are *not* reliable. In general tracking resource usage requires extensive profiling, and is really non- trivial. Slowness does not imply resource-hog. > > Experiment: Run gnome-terminal and xterm side by side. Not a fair comparison since they are not comparable feature wise.

I totally believe you! I'm not sure but this may be due to nothing more than differences in printing speed. gnome-terminal has to support multiple languages. I use mine in Japanese as well as latin. A more interesting test would be to do the same test in Chinese. > > Compile an application that makes gcc very verbose in each terminal. > With gnome-terminal, the overall system load is significantly higher.

Does microsoft have any plans to fix the "windows security sucks" bug? What you have isn't a bug, its a very general complaint that every gnome-terminal user is aware of. The people who are writing our desktops for us for free are very short of time, and implementing new features is a higher priority than extensively profiling gnome-terminal for a performance problem than may be *unavoidable* due to the multi-language requirement. If you want gnome-terminal to improve you need to provide more help than, "look at how slow this is!" I'm sorry there aren't infinite resource available to make everyone happy, but its just a fact of life.
