I have remapped [ and ] to easily cycle through my open buffers. I don't understand why when I use this shortcut there is a delay of almost a second before the buffer is switched. This doesn't happen when I use gn or :bnext. This is how do mapping: nnoremap <silent> ] :bnext<CR>nnoremap <silent> [ :bprevious<CR>Can you help me? 
Remapping [ and ] is really slow
