      Description

      In CASSANDRA-7594 we allowed configuring this. The problem is this was ignored for HSHA previously, so some people go through this scenario:

      1. start with sync and 4000 threads

      2. switch to HSHA, pre-7594

      3. upgrade to a version after 7594, without changing this setting

      4. experience awful performance due to insane thread contention
