When I save a file in Vim using
:w, Vim's entire UI blocks for about a second while it does something mysterious that (as a side effect) writes the buffer being edited to disk.
This takes way too much time. Sitting there like a chump for 1000ms waiting for Vim to finish the monumental task of flushing the buffer to disk is no fun.
My source file is fairly large (100k), and smaller files don't suffer from this issue, but 100k is really not that large. I consider a ~2,000 line, 100KB source file to be a reasonably sized buffer.
How can I speed this up?
