The size to use depends on the type of sites you visit (news sites with
constantly changing content don't benefit at all from a cache, while
sites with unchanging content you visit often will benefit.) I've got
mine set to 5MB. Just keep reducing the value and see what happens. You
aren't going to break anything!

mine to 20MB in the hope that would prevent the browser from getting bogged
down after heavy Internet use.
