On every image I take, I replace the delay from 500 to 100 and it is fast (too much maybe for some people) enough, 500 is far too much, you finished to type in a half second.

Yes, there is
Settings > Code Browsing > Code Completion... > Popup appearance delay
So I guess the question should be whether the _default_ delay should be shorter.
Showing popup immediately may not be so useful, because you haven't typed much...
I personally prefer to use shortcut to force the popup to show up.
