How come terminal vim take so long to open HTML files?

Question

I've been using terminal vim with custom plugin for a long-time. I never can wrap my head around this, I've been searching the web for a few days but had no luck.

I do a lot of web development, I use other IDE as well. They open HTML files almost instantly but in terminal vim it takes about anywhere from 5-15 seconds to open a .html file.

Question 1: Is there a reason for that?

Question 2: Are there any ways to improve the performance without resorting to using a separate IDE/editor?

My Setup

OS: MacOSX Yosemite

Vim: Terminal Vim 7.4

Thanks.

Is it taking time for only html file or for any other file also it is taking the same time. — smali, Aug 11 '15 at 05:00
@ali786 as far as I'm aware, its only HTML thus far. I've opened JS file and its almost instant. Stylus files are pretty quick, although CSS is slightly slow but no where near the level of HTML files. — TheLazyChap, Aug 11 '15 at 05:07
which flavor of linux you are using have you installed the vim. sometimes pre-installed vim gives trouble — smali, Aug 11 '15 at 05:13
possible solution might be try re-installing the vim --http://stackoverflow.com/questions/21012203/gvim-or-macvim-in-mac-os-x — smali, Aug 11 '15 at 05:34
@ali786 Thanks for trying to help, I prefer to know why. I'll keep looking, also that suggest using macvim or gvim which is definitely not something I'm after. I use terminal vim due to not having to open or switch around to other windows. Everything I need is in the terminal, I find it more productive this way. Thanks anyways. — TheLazyChap, Aug 11 '15 at 05:58
If you start vim like this: `vim -u NONE` (not loading any configuration or any plugins) does it still take a long time? Maybe one of the plugins or your configuration is causing the problem. — ap0, Aug 11 '15 at 07:06
@ap0 that is literally instant, I had a feeling it was the plugins as I have quiet a few but I don't know which one nor how to troubleshoot it :( — TheLazyChap, Aug 11 '15 at 07:08
This doesn't mean that it's the plugins fault. Remember we disabled plugins and your vimrc. To troubleshoot further use `vim -N --noplugin -i NONE` to only use your vimrc. And `vim -N -u NORC -i NONE` to only start with plugins. Then you will know for sure. Take a look at this: http://vim.wikia.com/wiki/Troubleshooting — ap0, Aug 11 '15 at 07:12
@ap0 It seems like the first command is causing the slowness, according to the guide its in the .vimrc. (Vim -N --noplugin -i NONE ) I've added my .vimrc file to the question. I'll probably disable line by line and see whats going on. Thanks again. — TheLazyChap, Aug 11 '15 at 07:26
Can you please also run `vim --startuptime vim.log` and add the files contents to your question? — ap0, Aug 11 '15 at 07:33
@ap0 I've ran the command as requested and uploaded the files content. — TheLazyChap, Aug 11 '15 at 07:43
Did you forget to open a html file with the last command? As far as I can see the startuptime was 150 msec. That looks fine. Did you run `vim --startuptime vim.log `? — ap0, Aug 11 '15 at 07:54
@ap0 Yes I did, sorry, its corrected now. I took your command literally, I'm not a vim expert. :( — TheLazyChap, Aug 11 '15 at 08:03

In the output of --startuptime you can see what causes the long startup.

If I understand correctly the files in the after directory extend the default syntax files with addition defintitions. A big portion of time gets lost for the vim-less plugin.

Try disableing vim-less plugin and see if loading gets better. Why this is caused by the plugin I don't know though.

How can I disable a particular plugin? Is there a command I can run to disable it or just completely delete the vim-less folder? – TheLazyChap Aug 11 '15 at 08:26
I took out the css.vim file in the after/syntax/ (not sure why its there in the first place) but its flying. Thank you very much for your help, greatly appreciated, as it was driving me away from VIM (something I love to use). – TheLazyChap Aug 11 '15 at 08:30
Try this: https://stackoverflow.com/questions/2888970/how-do-you-disable-a-specific-plugin-in-vim, so put in your vimrc `let g:loaded_vim_less = 1`. I don't know if this would be the correct name for the plugin. Try entering `let g:loaded_` and switch through the names with `Tab` Key. If it does not have the command, deleting the plugin folder is an option too. – ap0 Aug 11 '15 at 08:30
@TheLazyChap it is there because vim-less plugin put it there. It adds additinal highlighting to the default css file. – ap0 Aug 11 '15 at 08:31

I removed all plugins, then added and tested, finally found these plugins were the cause of slowness of opening html files:

'hail2u/vim-css3-syntax'
'mhinz/vim-signify'
