When using the bulk actions in Advanced Roadmaps the performance is not the same as compared to bulk updates performed in Jira.

By enabling the performance profiling, it is clear that while the bulk update mechanism in Jira is calling BulkEdit.execute() to execute the update, Advanced Roadmaps is calling DefaultIssueService.Update() on each individual issue, which seems to be the main cause of the performance difference.
