Hello, My company is running several clusters of memcache servers, each with ~ 100GB ram, running over 40 instances. Lately, I've looked at the slab statistics for some servers, and saw large variance in evicted_time between the different slabs, e.g., some active slabs with ~250s, and others with 270,000s. This behavior is causing us issues since we cannot predict when an object will be evicted from the cache. My questions regards the slab automove feature: 1. If I understand correctly, automove will move pages from slabs with high evicted time to slabs with low evicted time, hence trying to balance the slabs evicted time.Is my understanding correct? 2. Whats is the meaning of the "MEMCACHED_SLAB_BULK_CHECK" environment variable? how does it affect automove? 3. Are there additional args to control automove behavior?
Thanks, Shahar
