10 seconds for runs in first tab.
11 seconds for first run in second tab.
10 seconds for second run in second tab.

Could you test « by hand ». I'm not really interested in xterm, konsole etc.,
only gnome-terminal, because it's vte-based, like xfce4-terminal.

On recent xorg you need to explicitely deactivate compositing, with:

----8<----
Section "Extensions"
	Option "Composite" "disable"
EndSection
---->8----

On xfwm you need to check in Settings Manager, Window Manager tweaks, tab «
compositing » (wont be there if compositing is disabled in xorg).
