I don’t know (because I don’t use auto-bind), but I wouldn’t be surprised if they do. I avoid auto-bind, and instead let the user fill out fields and then hit “submit”, then the workflow writes all the changes at once. I do this because a) it reduces mistakes from someone typing in the wrong thing or deleting a value, which then over-writes the correct value with no way to revert; and b) it groups all changes into 1 workflow, rather than Bubble trying to “keep up” with changes being put in piecemeal.
I take the same philosophy with user searching – the RG is filtered based on custom state values; the user fills in the fields, hits “search” and then a workflow writes those fields into the custom state and the RG filter kicks off. That’s only 1 workflow and database call, versus multiple ones.
PS: in addition to various great posts on the forum about speed issues, this book is a great guide: The Ultimate Guide to Bubble Performance - the new edition is out (now 210 pages!)
