    Hello Martin,

    Thank you for contacting us.

    I tested the website, and while it seems to respond normally, please tell us whether the following link loads at the same rate as your embedded form:



    This could be caused by a number of factors:

    1. Your webhost web-server processes the Iframe fetch too slowly

    2. The general internet connection

    3. Slow response from our end.

    While the latter is unlikely, we will investigate nontheless.

    How did the two links behave?

    I couldnt open the first one, but the second one was extremly good! What does that mean?


    Edit: The second one only went good in the beginning now it's lagging a bit.

    thank you for answering my question. I try to describe what I mean by lagging. When I write something into the box and press Tab the form is lagging. 

    I just recognized when I write something write her in the chatbox it's also lagging a bit. Also when I change the font of  the clicking box. But I only have this problem on jotform homepage.

    Thank you in advance for your help.

    The reason why it keeps on lagging is due to the autofill feature. Currently, it is set to saved on every data changes which also means the autosave script keeps executing on the page every time you entered data on the fields. The 'save on data changes' works best on a short form. Your's a bit lengthy which is also the reason why. The best way to resolve this is to disable the autofill feature or you can adjust it's settings to saved with a time interval not on every data changes to prevent lags.

    Here's an example:

    I have also experienced the lag when I write my reply while the form is open in another tab. However, after closing it, the browser behaves normally so it's probably the runtime script that causes every pages to freeze.

    Hope this helps. Regards!

    I disabled the autofill feature as good as it's possible I think, but the form is still not working smooth. Did I do something wrong?

    This might be the form you've updated, http://www.jotform.eu/33321590996360 which is running smoothly now.

    But, the form (40284199440355) embedded on your page has still the autofill feature enabled. Kindly review.
