Subject Re: why the performance of counter is so bad ?

Briefly, counters read before write, unlike other writes in Cassandra.

Counters have been designed to allow for very fast writes. However, increment
does involve a read on one of the replica as part of replication. As a
consequence,
counter increments are expected to be slightly slower than regular writes.
