Profiling with below
nvim -c 'profile start vim.log' -c 'profile func *' -c 'q'
shows that neomake adds to the start up time. Currently we only use it
for two tasks. Running hlint for Haskell and stack build asynchronously.
Use asyncdo and define a generic wrapper command for running makeprg
asynchronously. This can be used for anything as long as makeprg is
set correctly.
vim-grepper also adds somewhat to the startup time though not much. We
do not need the functionality of switching between grep tools. Here
again just use asyncdo and define a generic command for running grepprg
asynchronously.
Drop QFGrep as we can use in built Cfilter plugin for filtering the
quickfix list.
Note that all start times mentioned above are a few milliseconds not
even more than 5ms. However, we would like to be as fast as possible
and use in built functions.

LSP does not work all the time. Either client breaks, server breaks or
it does not work because of the project structure. Removing LSP for the
umpteenth time.
asyncomplete does not seem to work at all for tags. For example, in the
gst-build directory the generated tags file can be 200MB+ in size. Even
with the file size limit set to unlimited it does not seem to give any
tag suggestions at all. Same is the case for Haskell.
Mucomplete can be slow in such cases where tag file is very large or
search space is extensively large and being synchronous this is to be
expected. To alleviate this, it is necessary to have a minimum prefix
length of 2 and perhaps trigger completion only when required. However,
this was still not good enough.
We are back to deoplete with custom source configuration. It is pretty
clear vimscript solutions are not up to the mark. Enable python provider
and also reintroduce language specific solutions like racer and jedi.
Refactor out language/file type specific settings. init.vim should only
have global keybindings, plugins and plugin settings. Also some other
minor cleanups, additions and rearrangements.
