"set showcmd" slows my cursor down in terminal

[mxgrn]

I note the slow-down both in and outside of tmux, in iTerm2 and Terminal on OSX. So, is this setting sensible enough?

[justinmk]

Is this in a remote session, or local?

[mxgrn]

Local.

Is this just on standard HJKL stuff? Having felt plenty of speed pain on OS X, it wouldn't take much for me to gut it.

Yes.

For what it's worth, there are definite speed issues in both Terminal.app and iTerm2 on OS X, for any terminal program which moves the cursor around to write to different parts of the window, rather than scrolling it. I've been debugging into iTerm2 to try to pinpoint precisely where they're coming from, but haven't been able to point at anything specific just yet. (I have a nasty suspicion that the bottleneck is the pipe between the PTY and the terminal application.. but I haven't been able to prove that yet)

These speed issues aren't visible in X11 terminals running under OS X; only in native apps.

I'm also experiencing noticeable slowdowns on OS X terminals (Terminal.app and iTerm2).

Also, blinking commands (particularly noticeable with repeating line motions (hjkl)) is distracting.

showcmd's principle use (for me) is a line count during visual selection. More than happy to compromise in order to resolve the above (selection line counts are easily achievable in other ways, e.g. g^G).

@tlvince are you confirming a clear link between 'showcmd' and slowdowns? I tried both terminals with and without tmux and I can't reproduce anything. Like I said, I'm not that attached to 'showcmd', but I'd like a bit more than one piece of anecdotal evidence before killing it.

@tpope besides slowdowns, I'm here because I did follow the link on README about reassessing defaults. Personally I don't like showcmd by default, for me it's just annoying and looks useful solely when debugging commands, so I'm inclined to enable it only for that, it doesn't improve in anything for an overral better vim experience in general. It just flashes in the bottom-right corner for nothing 99% of the time.

Would you consider removing it from vim-sensible? Meanwhile I'm looking how to preload vim-sensible on VIM-PLUG plugin manager, so that I can disable showcmd in my vimrc.

I ended up here because I was looking into https://github.com/junegunn/goyo.vim. I didn't care much about showcmd, but once I entered goyo mode this thing was jumping in my eyes :-)

@oblitum I use vim-plug and I load vim-sensible this way: vimrc#L18 and vimrc#L108 so then I can disable whatever is in sensible.vim that I don't like

thanks @vheon!
