Review link is taking too long to publish.

I have been using Articulate for the past 5+ years. But since the last update I'm having a big problem with the publishing course. It takes 30 minutes to publish a module of 20-25 pages. my one module has 40 pages, and it's took 4hr to publish. I also tested in higher configuration system, same result. I hope the articulate team is working on this issue. Please let us know if there is an immediate solution.
