I think noticing a slow redrawing and slow cursor movement on a fastest PC, is one of the popular frustrations with Vim. Here I am as a yet another instance.
I have a fresh installation of VIM, with the
$MYVIMRC at the bottom.
My problem is basically a painful slowdown of cursor movements and screen redraws, which are seen often after a while when
- lot many buffers parallelly open
- a longer sessions with multiple buffers used but not immediately after I start vim. They may not be the only cases though.
This is frustrating because, the problem is not easily reproducible. I cannot debug by line by line in $VIMRC, because I don't know how long should I wait to see slow down. All that I could do over the time is to observe the two above cases.
Can some of the vim-monks quickly see where the problem is in the vimrc below? (I copied all except a heap of
:nnoremap commands that I often use)

How do I debug my vimrc file? when I started vim in no-plugin no-vimrc mode, I see no slow down, but the default interface is not usable to me. I need some modifications as I did in above
$MYVIMRC. Hope you don't ask me to withdraw the whole
