Performance Issues with K2 Smartforms Designer
Diagnoses
We have a form in our environment that is very complex. It contains 43 views that are arranged on 14 different tabs. It contains over 300 rules and over 1000 bind-able controls (including the rules and controls that bubble up from the other views). It takes over a minute to open the form in the design environment. It takes about 30 seconds to open up a rule or open up an individual data transfer action. We get similar results regardless of whether we use IE 11 or Chrome.
Resolution
Modify the k2's host server file to point to the loopback address to the smartforms runtime url. We conducted a goto meeting and looked at the designer interacting with his system. The task manager identified his internet browser (IE & Chrome) RAM climbed and maxed out his local resources and would peg at around 750MB. It started reaching into the local paging file, which was set at around 2Gb of Ram. I looked up Microsoft's recommendation to modify the paging to multiple the amount of physical ram X 3.
