Caused VIM to use 100% CPU when moving cursor on some files about numbers.vim

[myusuf3]

OK, I removed all my plugin one by one and disabled the settings in my .vimrc file one by one.

It is

syntax on

cause the delay, any chance you can look into this issue ? I really liked this numbering

thanks

going to try some Java and C++ source codes and see what happens

No problems with a 4500 lines C code file.

I think I figured it out. Looks like Vim does not like "PreDefinedConstant" regex for ruby syntax highlight.

I removed those from ruby.vim, only lost few highlights but cursor moves a lot faster now, I also stopped moving line by line.

Together it worked pretty well as a workaround.

Thanks
