                description: The client output buffer limits can be used to force disconnection of clients that are not reading data from the server fast enough for some reason (a common reason is that a Pub/Sub client can't consume messages as fast as the publisher can produce them).

The range is between 1 and 500, however a value over 100 is usually not a good idea. Most users should use the default of 10 and raise this up to 100 only in environments where very low latency is required.

                description: The server's LFU eviction (see maxmemory setting) can be tuned.

The default lfu-log-factor is 10.
