Is there any point to incredibuild or sn-dbs? Helpers not being used.

I have agents/helpers connected to both sn-dbs and incredibuild but both don’t use any of the helpers when i build ue5 from source. Am i missing something? Here are my build settings. I’ve tried with xge being true and sn-dbs being true. Both are extremely slow and don’t use any helpers to build all 5700 items in UE5.

<?xml version="1.0" encoding="utf-8" ?> false true true true 8 2
<?xml version="1.0" encoding="utf-8" ?>
