vim is very slow on my Mac

Question

I use vim on Mac OS X, but this is realy slow in Terminal.app and iTerm.

Progress over many lines becomes tedious.

some idea of solution?

Solution 1

For me, deleting .viminfo helped.

Solution 2

Try MacVim. There is also a 64 bit version available somewhere on the blog, which includes a new rendering layer.

Solution 3

Maybe you have installed some broken plugins or something like that. Try to temporary rename directory with vim configs:

mv ~/.vim ~/.vim.backup

And/or main config file: mv ~/.vimrc ~/.vimrc.backup

And try to use vim without configs

Solution 4

I had this problem (just painfully slow) and it ended up being the Consolas font I was using in Terminal.App and ITerm Switching to Monaco in my case sped things up considerably

Solution 5

I regularly have problems, a few commands are just slow at redrawing. This is a shot in the dark but if you are using cursorline, try disabling it, it dramatically improved performance for me

Need more details. Are other commands slow? Does ps/top or ActivityMonitor show lots of CPU usage by other processes? Are you editing a very large file?

I only see vim slow. When I try down the cursor through of many lines, the processor monitor show many activity. No very long files, approxemately 200 lines.

Is this only a problem with auto-repeat, or is Vim sluggish when you enter text or navigate up/down with individual key presses? Have you checked your key auto-repeat rate in System Preferences?

I experienced the same thing and this solved it for me: superuser.com/a/513526/223984

I try with a empty .vimrc file, but nothing is better

my only solution xterm

not the issue for me.

Although this did make it slightly faster, it does not become nearly as fast as the same Vim configuration on a Linux machine without even deleting this file.
