I am using a Process Builder associated with a Visual flow. Can anyone could shed some light on how bulkification works for those? Right now the flow receives a record Id then do 2 Record Lookups + 1 Fast Lookup and 2 DML operation. Based on what I found (see link below) I should not run into any issue, but when I test it I can see that for each record I insert the flow will do 3 SOQL queries but regardless of the number of record it will do 2 DML operations.
And here is a screenshot of the Process Builder & Flow:
