Hi,

We have migrated web application from SharePoint 2010 to SharePoint 2013, there is a info-path form library, in that, when user trying to open a form (size 49 MB) it is taking 120 sec and at last it opens as "Read only mode", whereas in the same library another form (size of 48 MB) opening up quickly and no issues. Can anyone help, why the form with 49 MB size is taking long time to load and rest forms are good? Do we have any location that needs to check the session timeout which causing the form (size 49 MB) taking log time to load and read only.

Your help will much appreciated,

Thanks,

Hi, Nisanth.M

According to your description, in your info-path form library, there is a form (size 49MB) that takes long to open and can be read only.

As it opens as Read only, please check the permission of the form first. If the users want to edit the form, make sure they have corresponding permission.

There are various reasons why a form might be slow in loading. For example:

• Are there too many controls in the form?
• Did you add too many large attachments in the form?
• Is your form requesting a lot of data?

Here are some articles about the things to check when an info-path form takes too long to load:
