I have hit an issue that is causing a list and search page to load really slowly (~15 seconds+). I have a number of buttons of the Submit type in the modal position of the search form view. I noticed the issue was being caused by the Task in the buttons being set as Process (Ajax). The more buttons on the form with this Task, the longer the page takes to load. When I change the Task to just Process it fixes the issue.
My question is, what is the difference between Process and Process (Ajax), and why might this be impacting page load time?
