We have a SharePoint Site collection with a single root site having a few list and minimum data. About 10 lists and 10 15 records in each list. We have a single Nintex workflow for approvals. The approval has few stages and it uses if conditions, flexi tasks and send email notification for most of its controls. there are about 50 to 60 controls used in the workflow in total.The export size of the workflow is about 2 MB. We have cleared up the logs and tasks. we have also deleted the previous versions of the workflow. The issue we are facing is that this single workflow is occupying 210MB (analysis from /layouts/storman.aspx) of memory space out of the limited memory space that we have.
Kindly suggest ways to reduce the memory usage of Nintex workflow in SharePoint site.
