I'm doing an integration from Active Directory to Umbraco by keeping a bunch of user fields and photos in sync. It is just a simple loop looking up information/etc however inside of each loop I'm republishing each node because I really don't know if the photo had changed or not. The entire process seems extremely slow.

loop
   _contentService.SaveAndPublishWithStatus(node, 0, false);
end loop

Inside the loop I'm also unpublishing nodes if they are no longer in the active directory/meet a certain condition.

Is there a way to streamline the publish/unpublish so it isn't per node which seems extremely slow.
