WordPress automatically saves revisions when you are working on posts and pages. These can begin to add up pretty quick. By default, there is no limit in place. We have seen posts with over 1,000 revisions. Multiply this by 50 pages and suddenly you have over 50,000 revisions sitting in your database. The problem with this is that you will most likely never use them and they can start slowing down your database as well as using disk space.
So we recommend either disabling or limiting your revisions. It is nice to have a couple because we all make mistakes. So that is why we built in a couple options for you to choose from:
- Default (no limit)
- Disable Post Revisions
We personally like having at least 3 revisions, but no more so to keep our database small and snappy.
