It mentions TotalTerminal, which hasn't been properly supported since OS X 10.10, and outright doesn't work on versions of macOS newer than 10.12.

I really miss TotalTerminal. I've been forced to switch to iTerm, the only other way I can find to get a hotkey terminal, but it's an extremely noticeable difference to switch from the overall fastest terminal to the overall slowest:

Interesting read, never considered iTerm to be slow and I'm so grateful it exists but maybe I'm not as hardcore a terminal user as I thought I was :).

I'm not sure this is still the case or has been for some time. The maintainer of iTerm2 commented on it here https://gitlab.com/gnachman/iterm2/issues/5922 and here https://news.ycombinator.com/item?id=14800195.

Also recent versions include a metal renderer[3] (not sure if it's enabled by default) which might be even faster, I have been running it for some time but have not noticed much difference.

Another reason why it might be hard to notice is also because when one is using ssh you anyways have the network latency so might be one is simply trained not to react to latency in terminals as much.

For me, the most noticeable delay is in opening the hotkey window. I have animation disabled, and there's still a few hundred milliseconds between when I press the hotkey, and when iTerm appears.

Haha good call! I might well have trained myself to ignore a small latency :D
