I am facing huge slowness when i start the neovim for the first time in a session, and then next time i open it the startup time is little better relatively but not as fast as vim is. I looked at the issue tracker on official neovim git repo as well but couldn't find any solution for my problem.
So i profiled it a bit using startuptime and below are the log files.
1st time startup

Even i tried running nvim with noplugins option as well but even that also does not do much improvement which makes me think there is some setting that is causing the issue but i am not able to figure it out.
Any help would be much appreciated.
PS: I am new to vim/neovim and i really want to learn and work on it but this is somehow being a roadblock for me to use neovim. And i really want to use neovim because the advantage of having a built in terminal helps to get away from tmux+vim combo..
