[Too]

Does not work, i've also heard from other sources that turning this option on makes it faster because then it uses some native file-changed-hooks instead of continuously polling the directory. For me both options are equally slow and many forum posts say the same. Sourcetree performance simply is crap and no fiddling with the options fixes this, nor should this fiddling be required. You can find bug tickets about performance issues dating back years but nothing happens, don't waste your time on sourcetree just because it looks shiny, use a tool that actually works.
