    Description

      get_range_slice performance isn't that great. CASSANDRA-799 helped in the case when the memtable isn't flushed, but overall the operations per second and latency is still pretty bad. On a quad core node with a trivial amount of data I see around 130-150 ops per second with stress.py set to slice 100 keys at a time, and latency is 300-500ms.
