Business Rule script to copy work notes to associated cases taking a long time to run on problem

[ColinAngstadt1]

Hello

The script works, but takes almost two minutes to run when you update work notes on the problem.

Its an insert/update BR triggering when work notes change

var rec = new GlideRecord("sn_customerservice_case");
rec.addQuery("problem_id", current.sys_id);
rec.addActiveQuery();
rec.query();
while (rec.next()) {

rec.work_notes =  current.work_notes.getJournalEntry(1); 
rec.update();
}






(current, previous);

Thanks!
