Is pseudoterminal overhead perceptible?

[loveydovey]

It feels that there's ever a little tiny bit more snappiness when running some GUI app (nested wayland compositor) that was launched from a virtual terminal (using, say, KDE's .desktop shortcut) versus when launching it from a PTS from Konsole terminal. AI says there's overhead related to Konsole and the pseudoterminal. Would it be perceptible at all?

Konsole might render with GPU, and terminal output also slows down stuff (like warning-spam with compiling; I hide those to compile faster )

Ptyxis and GNOME Terminal with GTK do Vulkan with GSK_RENDERER=vulkan

yeah, the pty overhead would be perceptible. in slow motion. on an 8-bit CPU. running at 500 kilohertz.

on a computer today the measurement would be lost in the noise.
