How to get blog posts to update quicker

So I will write an EB post and then notice an error when it's published. I go in the backend and change the post, but for some reason, it takes forever to update. I've tried purging the cache on EB, then clearing the cache for Joomla under System and the expired cache as well. No luck, it still shows the old post. Then when it finally updates, sometimes just the post updates not the EB front page

It hasn't even updated to my new url, yet.

How can I clear the cache to make the update a lot quicker?
