I like gnome terminal except with each tab it consumes more and more memory. Some times I can actually see system slowing down and perceived delays in terminal response.
Recently I stumbled on to xfce4 terminal which is similar but takes lot less memory, lightweight and responsive.
Install xfce4 terminal
Install the package xfce4-terminal
sudo apt-get -y install xfce4-terminal
Use following command to run the XFCE terminal
