I've created a site workflow on Nintex 2010. It gets a few items (~3) with a query action and loops over them with a for each. All workflow actions are wrapped in a action set which runs as the workflow publisher that is an admin account.
I'm seeing some strange behaviour where the workflow runs in 2-3 seconds if I or some other test users run it manually. However, if a specific user triggers it, the workflow takes ~1 hr. There are no errors logged in Nintex UI or in the SharePoint ULS logs. The workflow eventually completes, it's just really slow!
The user has tried this from my computer with his account and it also runs slowly.
Can anyone explain or has seen anything like this before?
Does this user have extensive permissions in the SharePoint site? I've seen issues where a power user (added to many different security groups) experienced performance degradation.
