Often, if your forms have become quite long, you will notice that it starts taking time to load and even when saving forms. You can also check your internet connection as it may contribute to the lag.
I tried loading your form on my view but did not find anything wrong or any lag. If there is anything specific to which you find delay, please do let us know. This way we can also identify if it may be due do something else.
