Cache cleaner Pro

Hello,
I am interested in the pro version of cache cleaner, for auto cleaning.

But my question is: is it not a problem for the performance of the site if we activate an auto cleaning every 30 seconds for example? Or is there a minimum duration?

The fact is that I currently use Yootheme Pro on all my sites (about 30). The cache can't be emptied with the "Clean cache when I make a modification" parameter. So if I work on a site to make page modifications with Yootheme (or a client on his site), we see the modifications only after having emptied the cache. I want to avoid as much as possible that clients have to use a button to clear the cache if they make changes.

So far, I have never used the Joomla cache to avoid these problems.

OK, thank you. As i said, the goal is if a client make a modification, that will empty the cache.

So in the configuration of the plugin, you have a function for empty the cache at each modification. (see screenshot). But it dont work if i work in the Yootheme Pro builder and make modification. I thing it will work if i edit an article with the native Joomla editor, but not with Yootheme. So i search a way to force that.

But the auto cleaner will not be very usefull, as the client wont edit site all days...

OK, i will do that.
Thank you
