Hi @startupguys
I would export your field group to XML so you have a backup, then trash it in WP.
Edit the page and see if the JS lag has dissapeared.
If so, then yes, the issue comes from ACF.
Now, untrash your field group and edit it. Lets remove all conditional logic from it and again, check the edit post JS lag. Is there any improvement?
Add back in the conditional logic starting with any sub fields. These will most likely cause more JS processing.
Let me know what you find.
Thanks
