I wouldn’t believe how much this seemingly simple feature can affect rendering performance. Vim is being almost unusable when this is enabled. For more details, you can see my post at vim2hs’s issue tracker.
I used this feature for my entire life spent using vim, but after a few hours without it I realized I actually don’t need it.
In short, disable cursorline (or cul for short) if your vim renders/highlights text too slow.
