It looks like this loop is really quick with the patch applied:
% time zsh -fc 'for i in {1..700000}; do true; done'
zsh -fc 'for i in {1..700000}; do true; done' 3.24s user 0.22s system 99% cpu 3.466 total
But this 10 times larger loop is still really slow:
% time zsh -fc 'for i in {1..7000000}; do true; done'
zsh -fc 'for i in {1..7000000}; do true; done' 1136.44s user 4.39s system 99% cpu 19:05.28 total
