Hi , I am having 2 Cassandra cluster one with version 5.7 and second dse 6.7 both has same h/w configs and same configs but after performing read/write stress testing i found that latest version has more read latency than old as old is hitting key cache but new is not hitting to same. Please find attach cofiguration.yaml file and help me to parameter which should be change to improve read performance further. Also i cant see any parameter for key cache in new version ? how can we achieve read performance now do we need to tweak any other parameter ?My_config.txt
