This has been extremely prevalent recently, happens on almost every post I make.
I've done a bit of digging around and apparently this issue is as old as vBulletin itself, however there are many factors that can cause an issue like this.
Posting messages is the most resource intensive function of vBulletin. When you post a new message it must:
1. Censor the text in the message if necessary.
2. Convert all HTML entities to their proper notation if necessary.
3. Index each and every unique word in the post. (word and searchindex tables)
4. Send all email notifications out. (subscribedthread table)
5. Send all Moderator mail notifications out. (moderator table)
6. Update the thread information. (thread table)
7. Update the forum information. (forum table)
8. Update the user information. (user table)
9. Actually save the thread. (post table)
When you look at it like that, it is probably possible to look at individual processes on server side and pinpoint the source of this issue.
Most other forums that had this issue pinpointed it as a sendmail problem, so that could be main area to inspect if it hasn't been looked at yet.

One more thing I would like to add that is probably important: As you know first the page defaults to duplicate posts error. If you then quickly go back to the thread, your post actually won't be there no matter how many times you refresh, however, if you wait around 15 more seconds only then will the post show up. This means that the post is being delayed on server side even after the initial delay on client side.
Furthermore, when you post consecutively (like i did now) the delay is different. Instead of defaulting you to another page, it simply makes around 15 sec delay and then updates the post as normal.
Just trying to give as much information as possible.
I would encourage other users to give all the info you notice as well as devs can't troubleshoot this themselves.
