body: <p>I have a Redis Master and 2 slaves. All 3 are currently on the same unix server. The memory used by the 3 instances is approximately 3.5 G , 3 G , 3G. There are about 275000 keys in the redis db. About 4000 are hashes. 1 Set has 100000 values. 1 List has 275000 keys in it. Its a List of Hashes and Sets. The server has total memory of 16 GB. Currently 9.5 GB is used. The persistence is currently off. The rdb file is written once in a day by forced background save. Please provide any suggestions for optimizations. max-ziplist configuration is default currently.</p>
