    Hi, we are experiencing a significant lag time when someone submits a form on the site.

    Asked by Brennon24 on June 16, 2011 at 03:57 PM

     I just tested and the form can take up to 20 seconds to be submitted and redirected to the thank you page. Do you know why this is happening? How can this be improved?

    I tested your form using it's direct link - https://www.jotform.com/form/10202749205 - and I did not experience any lag time at all. Upon further investigation, I noticed that you are an old time Jotform customer. So I checked your site source codes and found out that you are using old (V2) Jotform embed codes for your form. This could probably be the reason why you're experiencing such a lag time.

    I think it's time to replace the old form codes in your site with updated iframe embed codes. Iframe embed codes is what I suggest that you use because it is the most fool-proof solution and it works perfectly fine for most of our users.

    To get your form's iframe embed codes

    1.  Go to Setup & Embed tab
    2.  Click Embed Form
    3.  Click iFrame

    4.  Copy the codes provided in the succeeding screen

    Let me know if this works for you or not. I am looking forward to your feedback. Thanks.
