we are seeing similar perf issues with counter writes - to reproduce:
cassandra-stress counter_write n=10 no-warmup cl=LOCAL_QUORUM -rate
threads=50 -mode native cql3 user= password= -name
op rate: 39,260 ops (4.1) and 63,689 ops (4.0)
latency 99th percentile: 7.7ms (4.1) and 1.8ms

replication factor is 1, you'd have to
Thank you all for the details on this.
