-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 intented 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.
