We are seeing high response times on the application side from the Java
Reactive DSE driver.
Cassandra server side metrics show response times of 2 ms but the DSE logs
show a response time (95th percentile) of 40ms.
it appears that the connections are open for sometime during a load run and
they go to 0, then again open-connections goes to the configured value
(4) + 1 and then again to 0.
Why is that ? Load run is at 30K RPM.
This happens even when I reduce the heartbeat interval to as low as 250
The CPU consumed by the container is just 35% of available.

Can someone help with this ?
