Benedict commented on CASSANDRA-6553:
-------------------------------------

FTR, if you want to run a mixed or read workload with counters, make sure you apply CASSANDRA-6835

> Benchmark the difference in performance between CASSANDRA-6504 and trunk.
> * Updating totally unrelated counters (different partitions)
> * Updating the same counters a lot (same cells in the same partition)
> * Different cells in the same few partitions (hot counter partition)
> benchmark: https://github.com/apache/cassandra/tree/1218bcacba7edefaf56cf8440d0aea5794c89a1e (old counters)
> compared to: https://github.com/apache/cassandra/tree/714c423360c36da2a2b365efaf9c5c4f623ed133 (new counters)
> So far, the above changes should only affect the write path.
