[RAC / FCF ] Oracle Service slow response

Hello guys,

We've noticed slow responding on RAC/FCF while we're using service that was created by srvctl add service command. It works fast without any delay on default service.

In short we created services via
srvctl add service -db orcl -service racfcf -preferred orcl1,orcl2 -tafpolicy NONE -clbgoal SHORT -rlbgoal SERVICE_TIME -stopoption IMMEDIATE -drain_timeout 0 -notification FALSE -pdb pdb24

Based on How to Verify Universal Connection Pool (UCP) / Fast Connection Failover (FCF) Setup (Doc ID 1064652.1)

Setup includes local_listener configuration too
How to setup LOCAL_LISTENER for RAC One Node Database (Doc ID 1497619.1)

Delays are randomly.. I mean sometimes we're able open application window < 100ms other time is 10sec or > 10sec...

Howdy, Stranger!
