Show download indicator only if download takes more than 2 seconds

@jonnyandrew I think we said on Google docs to show if it takes more than 1 second. Is it correct?

edit: maybe the value has been updated, now I see two seconds in the other doc 👍🏻

Sorry for the confusion. We updated it to 2 seconds after this conversation.
