Yes, always. I can immediately notice the difference when I type on lets a gnome terminal vs. xterm. But it's not only related to terminals. I have the same issue with editors. For example, the Atom editor is unbearable slow, VSCode is slow, Vim with a few plugins (incl. syntax highlighting and the like) is okayish and plain vi is fast. At least that's how I experience it. I decided to go with vim + plugins, because it provides the best tradeoff in terms of features and latency.
