-KeyDB will attempt to balance clients across threads evenly; However, replica clients are usually much more expensive than a normal client, and so KeyDB will try to assign fewer clients to threads with a replica.  The weighting factor below is intended to help tune this behavior.  A replica weighting factor of 2 means we treat a replica as the equivalent of two normal clients.  Adjusting this value may improve performance when replication is used.  The best weighting is workload specific - e.g. read heavy workloads should set this to 1.  Very write heavy workloads may benefit from higher numbers.
