High dispatcher cpu

I've had ongoing issues since moving to R80.x with high dispatcher core usage. We have 21800 gateways . We've had multiple TAC cases, they had us add a 3rd dispatcher core and set the affinity for the cores manually, but i still consistently see the 10Gb interfaces spike the dispatcher CPU's in what should be low utilization situations for this model gw.  We are on R80.20 jumbo 87, gateways were freshly reinstalled direct on R80.20 after continuous crashes across both cluster members in the last few days (will not be upgrading cluster in place again)..priority queues are off per TAC.

any ideas would be appreciated... put some info below for context
