Moving between form fields are very slow.

By filling out the form data, as they need to navigate between text boxes, long before the option is available to make the filling, this is normal, or have any configuration or anything I can do to improve and get better performance?

Hello MarciaRodrigues,

I'm sorry for the trouble caused to you.

I did test your form and I am able to replicate the issue you are having. The cause of this issue is because you have enabled the "Auto Fill" setting of your form. Please check the screenshot below:

You seems to have 640 fields in your form and when you start filling form fields, auto fill features start saving the form data of all 640 fields in cookies. That is the reason why moving between form fields slows down. 

To solve this issue, I would suggest you to please disable the "Auto Fill" setting of your form.

Hope this helps.

Do get back to us if you have any questions.

Thank you!
