Form submission is quite slow

Upon integrating the plugin into my form, it seems the submission takes a very long from 20 seconds to sometimes a lot more than this. Do you have any solutions for optimizing the submission speed? this issue really affect user experience and I wish to minimize it. I have tested on many forms such as WPForms, Contact Form 7, etc. They are all slow.

Hello,

By default Contact Form 7 / WPForms use synchronous email actions so the PDF generates upon submission.

Possible solutions:

- If you are using WPForms - you should be able to turn on the "Optimize Email Sending" option in the "WPForms" -> "Settings" -> "Email". This would make mail to be sent asynchronous and PDF generation would be made in the background.

Or

- Optimize the generated PDF to make it smaller size by reducing the PDF source (if the PDF is pre-uploaded) and use the "Flatten" option set to "Yes".

We would really appreciate your feedback at WordPress.org!

that works, thank you!
