how many elements you have in your form ? do you have any loops or repeaters ? making a small mistake like an infinite loop or a curl connection can of course break the form
Did you try to build a similar form on v8 ? v8 is generally faster but if your v7 form takes so long then its most propably a form setup issue

the backend takes longer in general, do you have other forms on the same website with almost the same number of elements which take much less time to load in editor ?

even though the timeout occurs at that line, the time may be consumed somewhere else, do you have the Safe Mode enabled in the v7 settings page ? if its enabled then something should be not ok with this form, I worked on larger forms without issues, just few seconds to load
in v8 you may set a field value using a function call, this feature is coming in the next update
