Cornerstone is Slow

[co50]

This is a general question that seems to affect all of our sites on modern versions of Pro. Basically, when we edit an element (something as simple as adding 2em of margin to a heading), there is a 2+ second delay before it takes affect in the preview. This occurs on every single site we manage that is on Cornerstone 5.x and up. On older sites that aren’t on an update plan, so they have Pro versions 3.x, edits in Cornerstone are near-instant. You add a margin and it instantly shows in the preview with no delay at all.

I’m trying to understand exactly what Cornerstone is doing after an edit is made that takes the preview 2 full seconds to update. I should add that I tested this on 3 different Windows PCs including Windows 10 and an extremely fast brand new Windows 11 PC. The result is the same on all of them. Any explanation here would be appreciated.

Hi @co50,

Thanks for reaching out.
There might be several reasons behind the problem you are facing. It is not only the upgrade of Cornerstone that has been updated; there is also the WordPress version updated, and the PHP version has been updated too. There are many plugins are there who didn’t update the code, which might be the reason behind your problem.
I would suggest you install the Pro on a fresh WordPress installation and let us know the result. I would also request you check the server configurations which is required for the updated versions of Cornerstone and WordPress are already available at your end.

Thanks

Hi,

We’ve conducted tests on existing sites with no plugins active, and fresh installs. The result is largely the same. Pro has a 1.5-3 second delay before changes made in Cornerstone are reflected in the visual. The only difference we’ve seen is it’s slightly faster on a brand new page with no existing elements.

I should note that we’re on a very fast server with tons of available RAM, generous PHP and WP memory limits, etc. Not that those things should matter because if I change the margin in a Heading the action should be entirely local and not dependent on the server at all. This is why I asked what exactly Pro is doing when a margin is changed because it seems like a lot is going on for this delay to be there. Would appreciate a higher level technical response that doesn’t point fingers at our server or other plugins, which we’ve ruled out.

Hi Greg,

This is really weird that you are facing such kind of problem, we have pointed out the very common reasons to narrow down the exact cause behind your issue. I have already checked the same in my local environment but didn’t find any significant deviation in the speed as you have pointed out.
As you have already checked server configurations and plugin conflicts, I would request you please copy your live site to a staging server so we could troubleshoot further and find the reason.
I would suggest you give us access to the secure note including:

– WordPress Site URL & Login URL
– WordPress Admin username/password
