We have a flow, and have noticed it has greatly increased the time it takes for a bulk (200 record) transaction to complete.
We've narrowed down the delay to a 78 second delay between FLOW_BULK_ELEMENT_BEGIN and FLOW_CREATE_INTERVIEW_BEGIN, with Workflow Debug Logs set on finer (the most detailed level available for Workflow). As we're unable to get any more granular on the logs, it's challenging for us to debug further. I'm opening a case with support, but wanted to reach out to here as well, in case others have noticed similar behavior.
For what it's worth, the flow is kicked off via Process Builder, and the first element is an 'Assignment' element, in order to bulkify this flow as much as possible.
Once we get into the flow, I am able to see logs for each FLOW_ELEMENT_BEGIN and FLOW_ELEMENT_END, and there seems to be nothing out of the ordinary, with each element only taking a few milliseconds.
