Symptoms

K2 Smartform - Navigate to another form action - Performance Issue
 

Diagnoses

We have a form where we have a rule where there is set of condition and according to the input value the form needs to be navigated to another smartform (by passing few data to its parameters) this particular navigation action is taking a lot of time (5-8 sec to navigate to other form).
 

Investigated client's environment and task manager

Resolution 

Large delays navigating to different forms. Diagnosis: .

The K2 server was slow because the K2HostServer.exe process was taking up a high amount of the CPU power (around average 55% - 65%).

A specific running process with a large state size was causing this.

Here is an article on how it was found: http://mikerodionov.com/2016/05/k2-host-server-eats-up-my-ram/ When the process was stopped and removed, it freed up resources on the K2 server and it started running normally again.
