Ho long does it take to for LinkedIn URL to update?

Hi.

1. If I edit my name on Linked in, my URL automatically updates, but how long does it take for the URL to update in public?
2. On a fresh Linkeind account how long does it take for the url to be available publicly?
3. Will connections fasten the process or make a difference in this regard?

It normally updates in a few minutes, but sometimes it takes a little longer to show up for everyone.
