    Slow loading of the form

    Asked by afckredieten on November 20, 2015 at 06:32 AM


    I have a ISP speed of 180MBps down and aporx 10 up

    form, has besides input mask widget no widgets. At the moment even the conditional logic is not completly set?

    See the screenreccording i took in firefox and chrome.


    (sorry fore the terrible audio, it was not my intention)

    In chrome i even have some more issues, you can see for yourselve. BEfore a field react on clicking it take some more time than in Firefox.

    I'm already worried of the speed embedding in the site, if the speed now is that slow.

    20/ 25 seconds is too sloow

    What do you propose?

    this is the form

    Firstly, thanks for the detailed question with screen captures. According to my tests,when I open your form, I get the same noticeable slow page loads as well. The slow rendering issue could be related to selected 'Save on data changes' option.


    To disable this option, you need to open "Properties", then click to the tab "Advanced Settings". Under this tab you will see the "Continue Forms Later". After opening the "Edit Auto Fill Settings" popup window, deselect the option called "Save on data chages".


    I hope this one will work for you. Please, try this one and let us know the results.

    In addition off the slow loading of my form, i forgot to mention that the admin pannel is also slow. It takes up to 24 sec to open a form, regulary it freezes, and in chrome i get the message page crasht wait or closing. For instance when i hit in topbar off the form publish in firefox, it also freezes it can take up to 40 seconds before i see on the right the copy link screen. If neccessary i could film the screens like i did for the form

    Since you have opted to store your form and date to our EU DataCenter(s), you will have to use our EU domain for your entire account. Please access https://eu.jotform.com and view the form using this domain. See if that makes any difference. If not, let us know so we can investigate further.

    Still, disable the auto fill in the form preferences.

    Hi again,

    In addition to what my colleague said, you have 480 fields and 26 conditions in your form. This could make your form load slowly. This one also causes slower load on "Form Builder" like you said.  In this case, I suggest you to lighten your form, if it is possible.

    the change to EU, i did after i wrote this first comment, so the filming and opening speed was before i made that change.

    Opening the admin is one thing, but it doesnt help the loading speeds of the form, i noticed that i'm not alone with speed issues? if not resolved i can't propose this to my clients, it's to slow the visitors will go away to other loan broker sites and make there demands there.

    No its not possible, in fact i need to merge this form with my calculator form, because linking is no solution.

    Are you really going to say that 480 fields is the issue? if i read the forum there are a lot of speed problems with much smaller forms than mine.

    Okay, what a bummer, i'm disapointed.

    I will discusse this with the clients, but i think it will lead to ending our subscription at jotforms and we will look for another solution.

    Even my calculator form with 20 fields is not fast. 

    Ok have a nice day.

    Hi again,

    Sorry for the misunderstanding, I should have been more clear about it. Of course, we are aware of the speed problem and we have been looking for the reason behind it; but generally, having that much field could cause a performance lost.

    However, I'm glad to see that you've found a solution for that one. If this one happens again, please let us know. You will be updated from this thread, if anything new comes up about it.


    Thank you for your understanding.

    Apparently the numbre of fields where the main issue of the slow loading speed of my form. So i removed aprox 170 of the 480 fields. let's say 30% more or less. With that also a lot of condional rules where eliminated.  I thought this would have an effect on te loading speed. Why else would you guys refer to it as the cause.  

    I would like to say, that the loading speed would improve, or at least that there would be a remarkable difference.

    Non of the above. In fact with pingdom speed test it 480 fields is faster than the one with 310 fields.??

    Even my pretty small car loan simulator with 40 fields or so is pretty slow, compared to for instance 123contactforms i tested

    Reduced form  https://form.jotformeu.com/53243729779368

    Complete form like it's supposed to be  


    car loan calculator



    Is there no way to resolve this issue? Even outside jotform, I am a newbee at this, i'm an amateure who's helping his family to make a broker website. Is there perhaps a way to preload the form in the wordpress site, so it opens faster? i tested it on a digital ocean wordpress site, and the result is even worse than the above pingdom screenresults. With a simple wordpresss without tons of plugins or slow themes. it's going to 22 seconds before it opens.

    Almost identical webform i made before coming to jotform, at 123contactform aprox 400 fields.

    the difference is ???????

    The reason i left 123contactform is that they don't have as much calculation possibility's. And jotform is better in design and a lot of other things, but speed is not one off them.


    I think i'm going to return at 123 contactform

    We fully understand your concern on this. But just to make clear also, having a lot of Conditional statements and Calculations on the form do have more effect on performance loading descrease of the form. The calculation scripts and conditions script will take more processing as compare to just loading fields/elements of the form.

    So this is something that you can use as reference when designing your form and as well as on how you intend to use them.

    Sorry but the form with 480 fields, which is almost = as my form at 123 has no calculation and identical rules because its the same form.... and there is a speed difference X5 faster.... so stop with excuses, when i google speed, loading issues jotforms its pages full of people with the same issue

    I've tested the form and it goes a lot faster like you said. Not yet as fast as my forms at 123contact and formdesk but considerly faster than last week, now i've got loading time of 6.29 sec compared to (see above) 15.98sec. Ok my forms at formdesk with 500 plus questions and more than 100 rulesets opens in aprox 2 sec. But ok this this is workable and i can propose to the clients.

    Yes i would like to be beta tester for the cdn

    There are also form specific issues that you should consider.

    Widgets are not cheap in terms of load time, for example there are about 23 Masked Input widgets on your form. Each widget is being loaded as a separate instance.

    Configurable list widget which is loading multiple links, plus response of the captcha field.

    Response of the translation script.

    Standard fields and conditions should be pretty fast at JotForm too.

    Answered by afckredieten on November 23, 2015 at 02:58 PM

    What the input mask concerns, used them as an alternative for a lot more conditions that i need to use otherwise. there are a lot of input masks that hides/show 5 fields or more each time. So one to make it easier in the backend i used them, and to i thought that more conditions would slow dwan te form also.

    I think there woud be at least 100 condtions instead of the 23 input masks. If you think that the conditions would be faster, difference in speed would considerable i can try it.

    2. what you mean with the other 2 is not clear, configurable list widget? what is that?

    and i only use one captcha.

    What does the response of the translation script means? my form is in Dutch is that what you mean?

    I must say, i'm testing the same form on formdesk and there is still a lot of speeddifference

    This is almost the same form on formdesk, which is 2X faster than my jotform.

    I would like to continou with jotform becouse there a lot more possibilitys, the usability is better, desginoptions, etc. But the client want i normal loading form in terms of speed. Becouse when embedding on a vps server hosted wordpress i suppose that the loading time will be going slower than testing the jotform with the direct link.

    this is the resulat of pingdom speedtest for the formdesk form

    Just an update in response off Mike his statement that the use of input masks had a neg effect on the speed/loadingtime.  I removed the input masks, and did not yet replaced them by rules (i think every input masks hide/show 4 to 8 fields, so instead of the 2 input masks i will need 80 to 100 more hid/show rules.

    Now, i wanted to seed what the effect was now the input widgets are removed.

    Unfortunatly, the speed did not get any better it even got worse???????

    The client saw this afternoon for the firs time his form i'm building, and he is happy with t fihe content, but if i don't get it faster in loading i will need to look for another solutions.

    Com'on you guys, i now that 400 a 500 fields is a lot for a form, but i can't imagine i'm the only one with this number of fields. 

    I'm testing formdesk as an alternative, i would like to stay becouse changing to formdesk would mean rebuilding from scratch.

    Here is an example of formdesk for +500 fields, the opening/loading is lightening fast

    This is there demo https://www.formdesk.nl/demo/speedtest500

    with pingdom

    this is the test off my form at jotform

    The difference is HUGE, i did a couple of tests (with the server at Amsterdam, i live in Belgium)

    and the fastest i managed to have my jotform was 7.72 sec, what still is 2X slower than formdesk.


    Hopening there is a solution on short tirme, becouse the form needs to go live begin december. I'm already worried what the loading times will be once embeded in the wordpress site (on a VPS managed server so on that end there is no speed problem).
