we are seeing similar perf issues with counter writes - to reproduce:
cassandra-stress counter_write n=100000 no-warmup cl=LOCAL_QUORUM -rate
threads=50 -mode native cql3 user=<user> password=<pw> -name <cluster_name>
op rate: 39,260 ops (4.1) and 63,689 ops (4.0)
latency 99th percentile: 7.7ms (4.1) and 1.8ms (4.0)
Total GC count: 750 (4.1) and 744 (4.0)
Avg GC time: 106 ms (4.1) and 110.1 ms (4.0)

Hi All,
Was going through this mail chain
(https://www.mail-archive.com/user@cassandra.apache.org/msg63564.html) and was
wondering that if this could cause a performance degradation in 4.1 without
changing compactionThroughput.
As seeing performance dip in Read/Write after upgrading from 4.0 to 4.1.
