9 years ago Looks like the syntax highlighting rules are expensive. Check the help at :h
syntime
Here is a patch, that tries to deviate the most expensive patterns on my system
(I have on around 60 lines visible (sorry no expensive monitor for me ;)) and
tuned the most expensive patterns. Check, if it works for you. Original comment by chrisbr...@googlemail.com on 13 Nov 2014 at 7:10

9 years ago I applied your patch. It doesn't seem that any of the patterns you modified
appear in my top 10 slowest. The rubyConstant pattern doesn't seem to match the
one in the ruby.vim syntax file, so I'm a little confused.

9 years ago I am looking at the before patterns.
Your syntime doesn't look that bad. I am surprised that your vim is so slow for
you. You could try to add '\<' in front of the rubySymbol just after teh \@<!
respectively the \@<= atoms and possibly at the end before the [!?]\= atom.
Does it work better if you 'set re=1' in your .vimrc?
Since the report doesn't look that bad, perhaps you could try profiling with
the latest Vim version?Original comment by chrisbr...@googlemail.com on 13 Nov 2014 at 8:12

9 years ago Im just chiming in to add that I had the same or a similar issue and 'set re=1'
made a huge difference for me with VIM 7.4 on Linux.
In ruby files larger than a couple of hundred lines the processor would spike
up to 100% and stay there for a few seconds every time I navigated up or down.
After adding 'set re=1' to vimrc it still spikes up to 35% but it's no longer
noticeable within the editor.Original comment by shara...@gmail.com on 3 Dec 2014 at 9:42
