number of items evicted decreases over-time

I have been bench-marking couchbase for the past few days, What I have noticed is that even you insert at a constant rate, the number of eviction decrease over-time which results in out of memory.
Does the process of eviction depends on CPU speed? or it is implemented in such ?
Couchbase must store key meta data for each item in memory. What is likely happening is that you are filling up memory with meta data and running out of room for values. I recommend adding more memory to your system. Also, note that we plan on removing the requirement that all meta data is stored in memory in a future release.
